A tale against myself

Ever since I bought the sailing dinghy in 2017, the inflatable has taken something of a back seat — as have the Moto Guzzi, the bicycles, the unicycles... I got the Zodiac out for one day in May last year, and I got it out again yesterday — which is twice in a rolling 12 months.

My objective was to test my new (second hand) 3 hp 2 stroke motor.

The Trent, near where I live, has been high for a few weeks now, and at one time it had flooded the carpark at the top of the slipway. It's back down to sensible levels now, although, as I discovered, the current is much faster than normal.

I arrived at the slipway to find another SIBber, setting up his Honwave. We had a friendly natter. I got onto the water a few minutes after him. The new outboard started 4th pull, ticked over nicely, and I set off upstream. I soon overtook the Honwave, which was trolling along at just over idling speed because he was running in a new engine.

Experimenting, I opened up the throttle. The Zodiac made a lot of waves, but went quite briskly. Not actually on the plane, but hardly a slouch. I was pleased.

Around the bend, the current seemed faster and I was making less than walking speed over the ground. I found myself ferry gliding to the inside of each bend hoping to find slower water. It was noisy and a bit tedious. After a while, I pulled up at the bank for a coffee.

As i set off again, I noticed something was missing. Hmmm. I know: the wheels! They should be sticking up, one each side of the engine. That meant... I pulled them up, embarrassed by my schoolboy error. I opened the throttle. My! What a difference it made: the boat got on the plane quite easily. The engine is noisy, but very effective.

I plugged on against the current. A journey to the pub upstream that normally takes me a few minutes looked like it was going to take another hour. Cold and tired, I pulled over again to rest, watch the wildlife, and have another coffee.

The Honwave went past, moving fast through the water, but making slow progress. The crew waved and shouted to check I was OK.

After they'd passed, I pulled out the choke to start the "cold" engine. It spluttered. I pushed the choke back in and it started straight away. I rotated the engine 180 degrees to reverse, and it started to climb out of the water. The anti-tilt wasn't working. (Half an hour with pliers, a hammer and drift, some WD40 and marine grease sorted that out when I got home.)

I decided I'd achieved my main objective, which was to test the engine. I was cold, and progress upstream was slow. I turned back.

A couple of minutes later, the engine started to sputter as if it was running out of fuel. I just made it to the bank, mixed some more fuel and started to pour it into the tank. I should have checked first: the tank was still nearly full, and I ended up spilling some into the river before I realised.

The motor started and ran for a few seconds and cut out again. I checked everything, tried again, same result. After several unsuccessful attempts, I provisionally diagnosed that I'd need to clean the carburettor. I knew the engine had been standing in a shed, unloved, for some time before I had bought it.

Enough was enough. I decided to row. It was easy enough downstream and it was warmer than motoring.

Back at the slipway after about 3 hours on the water. The best part of the trip was salvaging two fenders from the low branches of trees, following the floods. These are a useful thing to have in the sailing dinghy.

Back at home, I put the engine in the water tub and it started first time and ran perfectly.

I ran through everything. My best answer is that when I pushed the choke back in, I had twisted it as well without thinking. It's a combined choke and petrol tap. My previous 2 stroke 3 hp had a separate fuel tap and choke. I reckon I'd started the engine with the fuel tap off, run the carb dry, and then been checking by turning the fuel tap in the wrong direction!

Well, this shows me three things: the genuine value of a "shakedown" trip at the start of the season; the good sense of setting off upstream when testing a ew engine; and how easy it is to make mistakes and assumptions when using unfamiliar equipment. I've owned half a dozen outboards of different makes and sizes, but this is the first one with this particular combined fuel tap and choke knob.

And I'm out of practice. At one time, I was using the inflatable regularly for dive trips, and everything came naturally. I realise now that most of that experience was over 20 years ago, and since then it's been only once or twice a year.

I'm very pleased with the engine, and annoyed with myself, but sporting enough to share the story in case it's helpful. After all, humans are famous for learning from other people's mistakes.

Mike, Thanks for your story,
I probably only use our 1/2 cabin boat a half a dozen times or so during the summer in Oz, so have come up with a Do List for checking prior to getting the Trailer /Boat on the road and at the setup/return area at the Boat Ramp.

And the first trip out this summer, had a bit of trouble starting the engine, anyway got out to a fishing spot and when I went to move on the Merc 50HP 4s motor would not start.

It took a while and a number of non starts to realize I had not opened the air vent screw in the fuel Tank. Needless to say its now on my Do list for the Ramp.

Have not used my 2.7m Sib for a year with its 3.3 Merc 2s so will definitely need a Do list for it.

Peter

Launched a club rib the other week. Been sat over winter so I knew it might be a bit croaky

Fuel full
Bulb pumped up
Isolator on
Attach kill cord
Starting lever up
Key in
Turn. Splutter... Sounded like it was trying but not bighting.
Other guy launching shouts "check your fuel bulb is hard"
Moves to back of boat to do that
Return to start. Still turning over but not biting.
Just getting to the point we were going to pull her back out the water...
Notice kill cord is not in the switch. Either pulled out when attached to me or when went to check the bulb

Could probably do with a numpty check list that forces you to check things..I suspect if you 'know' the kill cord is on your leg you 'know' it's plugged in other end. Much like your fuel tap... "Must be on - boat was running just before"

What's the thinking on choke. I'd proby user it on a genuine cold start. For any start later the same day I'd try without then add it if needed ?

It was a cold windy day and I'd been sitting there 15 or so minutes, so I thought I'd better try the choke. I assumed such a small engine would cool off quicker than it did.

Be that as it may, it was a silly mistake on my part. If you compare starting an outboard to everything else that goes with setting up and launching either a SIB or a sailing dinghy, it shouldn't be as difficult as I made it for myself!

My claim to fame was the spring maiden launch of an Uttern 5m that i had purchased at the end of the previous season.

https://photos.app.goo.gl/NgkCvBZJkXaqT86P6

https://photos.app.goo.gl/2JAokCHv8qyvXdq96

Having spent the winter fiddling about, enthusiastically greasing and servicing everything that moved, the new season had arrived, and launch day beckoned.

I got myself parked up on the flat, at the top of the slip, removed the trailer board, checked the bung, removed the ratchet straps, still hooked on with the trailer winch, checked the bung, affixed mooring lines and fenders,.....and checked the bung.

The crowds were gathering, as i confidently began reversing down the slip,.....there was a little rumbling noise, so i stopped,....but the rumbling continued, followed by the agonising noise of concrete on fibreglass, as the transom/ hull ground its way down the concrete, as i preceeded to launch the boat onto the slip .....

I had been so paranoid about checking the bung, that i had forgotton to check that the ratchet on the trailer winch was set.....why wouldnt it be set??.... i normally leave it on, with a little tension,.....but the winter maintenance had involved taking a look at the winch and trailer rollers, to ensure it was virtually frictionless, and i hadn't reset it...... What a good job I'd done, the winch ran freely with the handle spinning like a swirling sword, as the strapping paid out in the wake of the boat!!

The incline on the slip was enough to let gravity take hold, much to the wonderment of the onlookers.....I was reluctant to get out of the van!!

I ground about 25-35 mm off the corner of the hull transom, and had to sheepishly fluff around recovering my boat from the slipway, .....3 hours and a bit of fibreglassing later we were stressed to death, but on the mooring.....!!

This was such a spectacular event, that i secured the "Wally of the year" award at the end of season club prize giving....... I'd spent the whole season desperate for somebody to upstage my faux pas, but alas, the trophy was secured!!

A harsh, but good lesson learned....

Done exactly that ones...i know exactly how it feels! Still can feel the walk of shame.... The bow went high and really lucky that the fin of the yamaha 90 did not touch the concrete...no major damage to the SR 5.4 either.

Update. Looks like it wasn't my fault after all. The engine did the same on the next trip. I've removed and cleaned the fuel filter, changed and correctly gapped the plugs, and it now seems to be working fine.

Left the bung out. Wondered why my feet were getting wet when lying down reading my book at anchor
Mechanic for some reason had tightened the pivot bolt so the engine was locked in the down position when I tried to install on the slip

1) Haha!

2) Nothing quite as annoying as a mechanic who readjusts something that was just right before. I had a motorcycle mechanic adjust the suspension on my Guzzi to suit his own weight rather than mine!
