Trip to Bunree

Wazzajnr · 19 March 2022, 16:38

Hi all,

Hope everyone is well and looking forwards to getting out on the water if you haven't already.

So, we're off to Bunree first week of April in the caravan, it would be rude of me not to take the boat so I figured it's about time to put the motor back together.
At the end of last season, the plastic bit on the end of the throttle cable broke, it had been glued together previously and some ham-fisted idiot had gummed up the swivel ball with glue.
Looking online and calling many many people resulted in zero hits for a new throttle cable.

So, armed with vernier and inventor, modeled up a new one and popped drawing off to the machine shop. Then work happened and it's been sitting in bits at the back of the workshop.

So, what did we learn today?

1. Evinrude didn't know how to make a good throttle setup in the 80's
2. My motor is a real triggers Broom, I have found parts from virtually every iteration of this engine from mid 70's to late 80's
3. The above said, it started first pull of the cord so I'm guessing the power head is pretty solid.

Put a new impeller in last year but wee hole still only drips rather than streams but there is plenty of water flowing so I'll just have to pop the engine up occasionally to check plenty is flowing out above the av plate. (I think this is because of mixed parts, the early ones didn't have wee holes, only the exhaust outlet just below the power head.

If I were planning to keep it long term then I would totally strip and rebuild but I'm hoping this year to get a bigger boat and motor. (thinking the boatworld 4.2m with a 25hp)

Anyway, any tips for places to boat to on Loch linnhe/leven would be much appreciated.

Happy boating and keep the wet side down!

Hi Wazzajnr, a few years ago when I was at Bunree C&MC site I launched a big (heavy) 3 person Old Town canoe, from the "beach" with a canoe trolley. I have also launched a GP14 at Ballachulish Marina it was free but that was a long time ago so things may have changed. The two things to note as far as I remember are the out flow just near the Corran ferry and at Ballachulish Bridge, but time the tide right and it wasn't a problem, in fact it was good fun in a kayak.

Hi Steve,

Yes I'm on the caravan club site. Last time I was there I was about 12 and rowing around in a kids rubber dinghy.
I remember being able to see the bottom easily it was so clear.
Yes, I remember the corran strait and the speed it flowed so kept well away from that in the rubber dinghy but now I have the bigger motor and can get on plane easily, I'm not as worried about it.
Does anyone know what speed it flows at worst case scenario.
No idea what the boats speed is now with this motor but I intend to find out this trip.
I've fitted some fins too to see if they help get on plane when I'm solo. Gets up easily as it was but need to get well forwards and my hope is that the extra lift will help balance it up better.
Not too bad when we're all in, swmbo midships and the boy upfront and it climbs out fine but with just me, it's a pain. If this doesn't work, it'll be arm extensions!

Have you tried a tiller extension?

Wazzajnr · 19 March 2022, 18:16

Not yet Steve. I didn't get much use out of it last year after I got the new motor, only one trip out to Anglesey.
I'll see how it gets on this trip but loathed to spend any more money on it if I'm getting a bigger tub.

Understandable

2 foot of old sink waste pipe and a jubilee clip...

Wazzajnr · 19 March 2022, 21:51

I would rather it just works.
I really don't like the idea of tiller extensions.
One thing I did notice today is that it's a 17.5" motor which probably means it's way too low which will give much more bow lift.
I might try lifting the motor a bit and see how it goes if the fins don't help.

Thanks willk, great idea

I've only ever felt the need for a tiller extension on a couple of occasions when it's got a bit rough, but one will be in Redneck for the next trip to Largs.

Have you still got the 3.2 Jago?

Noticed its only got 42cms tubes so I think you can assume that your transom is approx 42cms (16.5") so I think you are right presuming your 17.5" OB will be sitting too low.

Personally I would raise your OB and see if that helps before fitting any fins.

Wazzajnr · 20 March 2022, 10:48

Yep, same boat.
I'm going to get it out today and have a look at it.
When I got the new {to me} motor, I didn't have time, just pitched up at the beach and used it.
Yes, 42cm tubes sounds about right.

I cut a couple of longitudinal slits on the tiller end. Packing material if you have more "mirth than girth".

Wazzajnr · 25 March 2022, 18:45

Well, we have decided to stay a bit closer to home as the weather is looking a bit iffy so Porthmadog it is! 😁

Just had the motor on the boat and the av plate is a good 2" below the bottom of the boat. It's fair to say that the lever effect of this is contributing significantly to the excessive bow rise.
I'm printing out a series of spacers on the 3d printer so I can try it at different heights and see what the effect is. Just need to hope for some flat water for testing now!

Steve509926 · 25 March 2022, 21:01

I would definitely take the fins off, raise the OB so it's level with the bottom of the transom /keel and make sure the basics are right before thinking about refitting the fins.

Wazzajnr · 25 March 2022, 21:04

Yes, that's the plan.
If I had noticed it sooner I wouldn't have bothered with the fins.
I do remember when I used this motor for the first time last year, I got a lot of ventilation in turns at speed.
Hopefully, "getting the basics right" will solve a lot of issues........ Watch this space!

Steve509926 · 25 March 2022, 21:12

I think ventilation when turning at speed in a SIB is one of the things that comes with having a SIB.
It's striking that fine balance between being high enough to not cause leg drag & spray and deep enough to not bubble and fart at every turn.

Wazzajnr · 25 March 2022, 23:09

Well, we're going to have an early start tomorrow morning and chuck it in ullswater and see what we can deduce. I know we can't go fast there but with it sitting in the water we can see where the av plate is when running.
I've also done some work on the motor so I want to check it's good before we go to Wales next week.

Wazzajnr · 26 March 2022, 21:46

Well, around 17-18 miles covered today on ullswater and it was lovely apart from the last 20 minutes or so when we were into a headwind that brought up a light chop and it went really cold.
Motor performed well despite me managing to snap off the head of the kill switch getting it out of the car, quick snip of the cable and a bit of tape on the ends got us underway.

But.......... It was kicking up a right old rooster tail on plane, managed to find a sweet spot where it wasn't flooding the back of the boat. Hole shot with the doel fins I think is fractionally better but that's debatable but they certainly were causing the majority of the spray.
The motor is Definately way too low so week after next in Porthmadog, I'll try some spacers to lift it up. I did take some today but they didn't want to stay in place and I wanted to try it as it was.
I'm just pleased that my triggers broom motor managed a good long run without missing a beat.
Chewed through about 10l of fuel (rough guess) which I don't think is too bad for 18 miles 3 up

Some pics. 😁
