Sorry to disagree on some points , a long shaft engine will start as fast as a short shaft engine, will depend entirely on engine health, that's well tuned to perfection.

The only issue that will experiment using a long shaft on a short shat transom will be a huge water splash out transom at plane if that engine can have the power to plane a 320 sib easily. If only can achieve fast displacement non planing speeds not an isssue. Go for any 2 strokes, less weight.

Will add being a longer shaft means will need to boat with caution on shalow waters or risking bumping lower tail against hidden rocks, sand beds, etc.

For peace of mind and wallet, ask seller if that's a short or long shaft engine ? You can always add a 5" transom mount or a second water deflector for that long shaft to work perfect on a short shaft transom.

That offered 5 HP looks a short shaft to me, compare to this S one...

Happy Boating

Locozodiac, the owner says it's a long shaft!

It's a pity because that's probably the best engine I've found so far.

I dont see it as a disadvantage, I love the smell of 2 stroke oil in the morning

2 stroke V 4 stroke has been done to death, have a search on the forum.
I'm undoubtedly a 4 stroke guy, especially when talking about bikes. But when it comes to this kind of boats I think simplicity is the key an it's a shame 2 stroke engines aren't being produced anymore.

Have my doubts a 5 HP will plane a 320, if so, probably with you alone, if being a feather champ with lightly loaded sib. Is it possible to trial that 5 HP on your 320 before buying it. Talk to owner, would be my best advice.

Wrong, 2 strokes of most brands are still being built, just don't see them any more on countries that have banned them. We currently import 2 strokes Tohatsus 3.5-5-18-30-40-50 HP engines. We're a smoker country..

The posted owner pic does not corresponds to a long shaft, tomarrrow will post a long shaft engine pic.

Happy Boating

Unfortunately the guy lives 200 km away from me so it's very hard to try the engine on my sib before buying it.

I'm not worried about the splashing because from the videos I've seen a 5hp won't plane my boat. My main concern is damaging the engine on some hidden rock or when I get to the beach sand. I'm mostly gonna launch the boat from the beach so I would have to be even more careful.

You edited your post and got me confused...

I didn't know that. I assumed they were no longer being produced because they're not for sale in Europe.

Hmm... I'm gonna talk to him to see if he made a mistake or posted another pic. Maybe there's hope!

I was wrong, Loco is right, I should have looked at your link.

Heres a picture of my 2006 Tohatsu 5hp, it was definately a short shaft, and it looks identical to yours.



Small 2 strokes are not banned in Europe but emissions regulations from 2006 made them non compliant and you cant import them anymore. They are still available all over the world (including just across the water in Alderney), but not in Europe

This is a long shaft engine:

So you went for it if being short or long shaft ? Long shaft engines have longer middle section than S size. If the 320 won't plane not an issue issue using a L size. You can always pivot engine to change angle when boating on shallow waters, will have plenty of water for prop to grip and push sib well.

If it's mission impossible for boat to plane it's much better to throttle enough to maintain boat riding near paralell to water level at just fast displacement speed than fully throtttling and achieving bow up which causes excessive hull drag and engine striving unnecessarily along. Much more engine stress if heavily loaded.

I didn't go for it. I'm still waiting for some photos from the guy before I make a decision.
