That's something I know nothing about.
The idea sounds great, but I can also see the disadvantages, One to mull over.

Lots of knowledge passed on in this thread so far, all being taken in and a big sigh of relief knowing I've got you lot to tap into. I owe you all a pint*









*I reserve the right to retract that statement if and when you take the pish coz I know naff all.

You'll struggle to source a decent second-hand 2-stroke Yamaha 50hp, although anything is possible. Actually there was one for sale recently on Ebay (Skye), long-shaft and had been used in fresh-water, a snip at 2k!

If you do spot one - you might need to buy the bucket it's attached to. That's the reality of the second-hand market just now. Good luck.

Had a look at A1 National and they don't seem to carry much stock of used motors. I know Pete7 said not to go to Bill Higham but he does have a lot of stock and the prices don't seem that bad do they? Like the sounds of a bit of warranty too.

Two motors that I've seen are a Honda 45 4 stroke and a Mercury 50hp

That mercury is at least 25 years old-and the Honda is no spring chicken either.

He's asking at least double their worth for both of them too.

With a short hull weight is critical or you will upset the balance of the boat, hence our recommendations for 2 strokes. That Merc 50 hp is likely to be 1970s. The reason I said don't go to Bill is that he is very expensive and really only as a last resort.

The 3 cyl Yams and Mariner/Mercs will command a top price however this would do nicely. Okay its hand start but pull starting a 40 hp isn't difficult and means you can then get away with using a small motorcycle battery (saving space and weight) for electrics like a radio etc. For the price a late 90s engine will be much more reliable than a 30 year old Merc. Bembridge are members of Ribnet and built some very nice Shearwater cabin ribs. Having bought covers from them and visited several times I would be happy to recommend them.

Is 40 hp enough for a 4m rib? yes, I think that Merc 50 was rated at the powerhead also any wear will have reduced the power output, whilst the Mariner 40 will be at the prop,

Thanks lads.
The only reason I was thinking of a 4 stroke was for running costs. Paying out for petrol and the right 2 stroke oil just seems a bit much when the price between 4 strokes and 2 strokes doesn't seem that great.
But like you say, it's all down to the weight.

That 40 hp looks a good motor, only thing is is it's location. Will have to contact them and see how much P&P would be if they do it.

IF you see a good 2 stroke with power trim/tilt on your travels will you either PM me or contact me through www.johnsingleton-photography.co.uk ?

Thanks for your help!

Don't get hung up with the hype about saving fuel with a 4 stroke. At tickover yes the honda might be 30% more efficient as there adverts says, but that is 30% of say a gallon an hour, hardly worth getting excited about. At speed however the difference is likely to be much smaller. In the 130 to 150 range we have seen old 2 strokes use less than hondas 4 strokes.

Long time since I used a Mariner 40 but would have thought 15 - 20 L per hour constantly flat out and obviously less for cruising or water skiing etc.
