What's your plan?

If you did sell it as a package I can only think of one suitable replacement and it goes by the initials SR

Thanks All,

Unfortunatly there is no budget for changing the engine, certainly not for a year at least. Looks like i'll have to be dissapointed then

Maybe I should have done a little more reasearch first before buying it

Max is 150hp on that hull. So its no surprise that max speed is modest and you only get that at WOT.

I have a 60hp Yam, but its on a boat 5ft shorter and more than 100 kilos lighter.

Sell the 60 and get a used 100 or 115 (or more) if you can. If you shop wisely you can reuse your existing controls and cables.

the 560 was rated to 115 and the 620 was 150 Capitan. we over here it is im sure

Oh oops I thought it was the bigger hull. Whatever it is, 60hp is far too small!

I have a 60 etec on a 4.9m rib. this engine size is right for that size of boat but not for a rib of your size

Yeah alright don't rub it in!!

[beamishken]

just save up for another engine the same and install it beside the origional job sorted!

All joking aisde, I'm looking ain a postage stamp sized window of your photo (at work! ) - is your transom flat across the top? If so, Beamishken's suggestion isn't so daft...... (and before you all go down the "twin vs single" arguments let's not start that all again here.... )

Also dinae fasch yersel' - pretty much everyone on here would say 40 HP minimum for an SR4. I drove mine around with a 25 on the back for years and happily cruised at 20 knots. I now have a more suitably matched engine & boat....and still cruise around at 20 odd knots! Granted at 4500rpm rather than the 5500 I used to.....

Assuming it's power trim, have a play with that - you might eek another couple of knots (or reduce the revs a bit) by trimming it right.

Moving the weight around (anchor / fuel etc) might also help - the less Hp you have the more critical that becomes.

Just been out for an hour in it with the better half. Good fun up the estuary...got drenched! Love it!

Can anyone (and I know people hate this) give me an idea what my engine is worth 2nd hand. I'm weighing up my options at the moment and see if I can scrape together some cash for a slight upgrade. It's a 2011 or 2012 Mercury 4 stroke with very low hours, at a guess 20-30. Just been serviced again last month.

How do you tell exatcly how many hours? Presume it's stored in the ECU? Do you need diagnostic equipment to read it or can you just plug a gauage in?

Thanks dude. The anchor sits up the front in the hatch in the bow and there is a sizeable aluminium fixed fuel tank under the main console so probably not much can be done there. I like to keep it half full when I'm just messing around on the estuary. I'll have a play with the trim when we get a nice calm day in the meantime.
