Hi

I have a YAM 310S with a Mariner 10 and this planes with 2 onboard (in flat seas). Unless you're very light I would suspect that 6hp will not be powerful enough.

9.9/10 perfect for a 310, if more budget available and your transom supports it, (see plate) go for a 15 HP; 2 strokes weights 7/10 less kilos compared to 4 stroke same brothers.

Hi there, I have a 6hp Evinrude on my Avon Rover 3-10 and with 2 people and a bit of fishing gear it will struggle to get on the plane. If I borrow my brothers 9.9 however, it will get there.

With just me on my own, either engine will get it on the plane but you have to move your weight forward and find the right spot for it to do that.

I have an 8hp on my 3.10 Yam (wood floor). It will plane with 2 adults and 2 children.

I think some 6's are single-cylinder, and some are twins. Suspect a 1-pot 6hp engine may not be the way to go. Twins make better engines anyway.

Age is a factor - does an 80's engine with unknown hours definitely produce its rated power?

As said I think you will be disappointed with a 6HP & will not get on the plane with more than 1 up & then you will have to be well forward to do it!

9.9/10 will be a fair bit heavier to lug around: around 36kg, compared to around 25kg for a 6hp, but a much better choice. I've ran both a 6hp and a 9.9hp on an Avon 3.15 with rollaway deck and as exerienced in earlier posts, with 2 adults onboard, it struggled to plane with the 6hp, but flew along with the 9.9...... and still does - I've sold the 6hp

I would go for a 15hp (assuming the boat is rated to take it), although a 10hp would probably be OK most of the time. Don't get a 6hp motor and expect to go anywhere fast.

Think of a 6hp as using a set of oars, but with fewer calories expended.

Me 2 assuming that you are looking for 2 strokes engines, both models 10/15 HP weights the same (evinrude/johnson 36 Kg) (mariner/tohatsu 41 Kg/) other brands don't know, if not on tight budget, go for the 15 will serve you ok with a 310, and also if in a short future would like to update to a larger 330-340-350 sib. If not, a 10 will perform perfect, just balannce sib & buddys well and inflate correctly.

Happy Sibbing
