Will a 10hp motor get my Yam 340S onto the plane?
 
I had a 15hp Mariner outboard with my Yam 340S SIB, and it performed well, getting the boat onto the plane, and a top speed of 15 mph.

Unfortunately the engine was stolen at the weekend. :mad:

To replace it I would like a 10hp motor, because it might be lighter to carry, and use less fuel. And perhaps a little cheaper.

I don't mind if it is a little slower, but I still want it to get onto the plane. Is this still going to be possible with a 10hp motor?

Thanks

How many people and how much kit will you be taking with you then we can give you a better answer?

Two stroke with no kit in good condition. Of course it will.

Put this way i had my 3.8m boat, 9.8hp merc, 2 adult and 5 kids (age 5 to 9) it only just got onto the plane against the tide coming back up the river.

Doesn't matter which way the tide's going.

Just me (72Kg). No kit.

So it looks like a yes then :)

Thanks all!

Hopefully I won't get my new motor nicked too.

I think I was a bit unlucky with the current one. I had tied my boat up on a disused dredging boat on the Basingstoke canal near Aldershot (UK) specifically to keep it away and partially hidden from a car park adjacent to the public slipway there. I was only gone 2 hours during twilight while I returned to Winchfield to collect my car. The thief had to jump a 80cm gap between the dredging boat and the canal bank carrying the motor at the same time - must have been more athletic than me!
And they had it away with a 3/4 full 50-litre fuel tank too.
I reported it to the police. But I can't expect them to find anything.
It was only an old motor which was a beggar to start. But I had grown a little fond of it <weep> lol

Bear in mind your proposed 10hp may be the same outboard as your 15hp but with less power... i.e. weighing the same. If you're going to carry the weight of a 15 at least enjoy the power of a 15.

Are you up on the plane on the Basingstoke canal?

Well I do confess to giving it a bit of welly once or twice on the trip. But 18mph is a tad over the 4mph speed limit so I didn't do it more than a few seconds.

Apparently the wash from high speeds can damage the banks of canals and rivers, so I kept my speed down..

50 litres??? where were you planning to go? :)
