Cheers Bruce approx 4 kts will do for me . I know people say a bigger engine is better but on a small boat 5.5m there simply isn't room , and lifting any more on and off is a struggle .

I have heard some tohatsu's are prone to eating the odd coil but who knows . My gut feeling is although Tohatsu make engines for other more expensive manufacturers their own may be pared down a little somewhere so that they sell cheaper . ie although for instance the merc 3.3 is a tohatsu 3.5 is it assembled and finished by merc to a higher standard ??

I think mercury use better quality materials for some of the parts. At work we have about 20 4hp 4 stroke mariners, and 2 mercury 4hp 4 strokes. The mercury outboards outlived all the mariners fitted the same year. One eventually gave up in the autumn, when the transom bracket casting failed, and it went under (it wasn't worth getting it running again)

I have a 5hp tohatsu, with several hundred hours on it, its left on the boat, which is on the water all the time, I've never had any problems with it. Neglect and lack of use is the probably biggest killer of outboards

I have a 60 2 stroke on my tornado 5m and it performs great with a light load and is just ok for 4 divers and the kit. When I replace the engine I will go for a 70 - 80hp probably 2 stroke. I think you will be disappointed with anything less than 60hp but might get away with 50hp.

Good hunting

It may be well respected but I found in the application of sticking it on a RIB transom it wasn't very reliable, but this was just my experience.

Should use a proper marine grease to have all linkages working properly. A outboard must be started/used constantly.
I did, it was the alloy carb in particular that seemed to corrode rapidly which seized up all the linkages running through it, several times in the two years I had it from new.
The other thing you have to consider is fuel. I found it easier to have a FS aux as the testing and fuel on board was easier to fill up etc for regular testing.

I had a 60 Yam TS on a 5m hull, did about 24-26knts depending on load.

Anyone got any comments good or bad on a 1988 Suzuki 65 hp 2 stroke? Is it the model after mine ('82) and was it an improvement?

The paint work wasn't a strong point on grey/gold Suzuki's (paint on there bikes at the time wasn't much better either) so they tended to corrode into a horrible fury mess if left in damp conditions. That engine is now 20 years old, if it runs and is in good condition it might be worth a punt but only if its cheap.

Given a choice I would much rather have this though:

and e bay your Suzi in the spring.

Saw that one whilst browsing. I'm quite new to outboards and got stung with the DT60 so I'm a bit wary of buying privately. The Suzuki I'm looking at is from a dealer and has a 6 month warranty for the same price as the Yamaha.

Think this one will be one of the medium V Ribs rather than a Seafury, which were good boats.

Bigj, have you seen this post, Paul may have a 60 hp 2 stoke Merc for sale

http://rib.net/forum/showthread.php?t=22871

Nice little engines, rumoured to have been designed by Yamaha for Mercury when they first came into the county in 91/92 time. Used one for a trip round Scotland, just kept going flat out every day for a week without complaint. About 5 gallons an hour at flak speed and the oil tank is self contained in the engine to make a neat installation.

Thats the one i'm buying for my 5.3 Humber but I won't be able to test it until the 29th January. It's difficult being patient in the mean time. I hope 60 is enough.
