I need a new engine :(

My engine is buggered. After 2 days soaking in the strongest penetrant I can find the l/u still won't budge even with half a tonne pressure on it. Arse.

Looking at a 60hp VRO evinrude-is this likely to be too heavy for my sr4?
Don't suppose anyone has a 40-60hp knocking around they can sell me for up to 600?

There MUST be a way - have you tried heat on it?

What exactly is stuck?

The driveshaft is frozen into the powerhead. Can't put heat on it, it'll bugger the bottom crank seal and I'll have to cut a big lump out of the side of the leg to do it. I'm now getting nervous that I may damage the crank if I use any more force.

I've put so much through the casings that the leg is starting to crumble at the joint.

I DO have a spare S/S driveshaft but I really don't want to dismantle the l/u on an 80's saltwater engine to remove the old one after I cut it apart. I doubt it'll seal properly again.

Doesn't sound good NOS, I assume your mechanically competent but it may be worth taking it somewhere to get it looked out? I assume you were trying to change the impeller?
Used engines wise this time of year 600 doesn't buy you an awful lot, the old twin carb Mariner 40's (produced by Yamaha) are indestrucable, and produce good power, a mate had a 1978 one and it was brilliant, better than my Suzook 2stroke 40 any day. For 50/60hp's the Yamaha 2stroke us hard to beat but is also quite expensive.

This ones tasty but well above your budget, still cheap though!http://www.boatsandoutboards.co.uk/view/OAB305

http://www.boatsandoutboards.co.uk/view/F98155 same as yours, seems cheap

http://www.boatsandoutboards.co.uk/view/F96615 Good value!

best of luck with it

Unfortunately that merc's not the same as mine-it's from the early 70's and a museum piece or I would have grabbed it by now. ROUGHLY the same powerhead but different (and crap) ignition and a different saddle so my PTT won't fit.

Just the wrong time I guess.

That Mariner looks like a good idea. I've got my eye on a 1990 60hp VRO Johnson as well but not sure about the weight on an SR4-they are 104kgs-maybe a bit less as the VRO has been removed. Any opinions on it?

The Johnsons. aren't bad they smoke abit, but get on with the job in hand. Ollyit has a Yammie 60 on his, not sure of the weight of them, and im sure I read David Manning put a 70HP on his
Having the VRO removed is a good thing

The 60 VRO and the 70 VRO are apparently based on the same engine so you can see why I was wondering about the weight-did David Manning run a Johnson triple?

I DO like the idea of 60hp at the prop rather than the 45 my merc puts out.I've clocked it at 38mph on GPS and no tide with the merc. I think it'd be rather fun with 30% more power...

How old is this buggered engine, just out of interest?

Also wondering why taking the VRO off is a good thing (as a Johnson owner) does it cause bother?
