Engine for Avon S310 Sportboat?

[auluslesbains]

I have bought an oldish Avon S310 Sportboat SIB with a wooden floor - and can't find info on what size engine to use or what the maximum load is. I want to be able to get on the plane with a fairly heavy load of equipment on board. Can't find a spec sheet anywhere. Can anyone help?

A 15 HP short tail will be fine, if 2 strokes available the better, 10 kilo less compared to same 4 strokes model. If bit more power is needed, go for a Tohatsu 18 HP.

It I think may have evolved into this:

In which case you're talking in the ballpark of 10Hp.


Having said that, the numbers on the scan here http://rib.net/forum/showthread.php?t=32256 hint it's more likely related to the Current "heavy duty workboat" http://www.avon-workboats.com/page/w400, in which case it may take more.

Maybe if matt reads this he might have the rest of the brochure with the smaller hulls' info to hand.

avon s3 .10 in my book says max 10 hp--- 7.5 kw and a rough guide to speed with a 10 hp ,,1 person 19 mph,,,,2 persons 16 mph ,,3 persons 14 mph as i say is only a rough guide to speed .and capacity can carry 934 ilbs,,,or 420 kgs ,,,or 5 persons

Thanks guys. Great stuff. I wonder if Matt H has a picture of the Sportboat 310 (if he's still on the forum)? The data for the Sportboat S340 suggests the 310 will take 15-18hp, whereas as m chappelow says, the current 310 seems to have 10hp as a maximum. I do like the idea of the 18hp Tohatsu. :-)

If it can handle a 10 HP, that is a 9.9 will also handle a 15 HP 2 strokes as both engines weights same and have 250 CC each. Tohatsu 4 strokes is another story, 9.8 has 210 CC-37 Kg compared to 350 CC-52 Kg for the 15 model. 15 model has same weight and CC as 20 model, so check transom specs for max engine for Sportboat 310 sib.
