Anyone in south with Tohatsu 9.9hp 2/s?

Hi Guys

I have a 3.2m Honwave with air floor, and an 8hp Tohatsu 2/s - with me and the 6yr old in it, we can pop on the plane really easily... however, add anymore weight then it is a bit more difficult... with two adults and two kids, its very close but can't get on the plane.

I was wondering if anyone near me in Southampton has a 9.8/9.9 Tohatsu which I could borrow/hire for a few hours to see if its worth me upgrading my engine?

Thanks

Ben

I take it that you know that the 9.9 is a very different thingumy to the 9.8?

Well, the 9.9 is 41kg, the 9.8 is 26kg. That may help in the decision making process. Of course, the 9.9 has much bigger cc, so probably more torque?

IIRC the 9.9 is a variant of the 18hp, so a 15/18hp might suit you better...

As willk says forget the 9.9 - *much* heavier than the 9.8 so you would be much better off with the 15 or even better the elusive hen's teeth that is the 18 - need one myself if you find two!

Weight distribution is really important in these small SIBs' - we have a 3.4m air floor Zodiac and a Twatsuuu 9.8 and 2 small kids - you need to get the weight well forward to plane then back as she gets going. With one adult + 1 kid it's a doddle.

Ah, didn't realise the weight difference was so big! So yeah, going to be the 15 or the 9.8 then Don't suppose you know if i can get any more power from the 8hp? I found it hard to find any accurate info on the net about possible conversions

the 8 and the 9.8 are the same block - dunno about upgrades.

My 2.7/9.8 combo will easily plane with 30 stone onboard - not sure the 9.8 would do the job you ask. John Kennett will know the answer - he was running a rig and load like that. I think it was marginal...

As above we're around 28 stones and the 3.2 with 9.8 is fine. The 15 would be better though...

Ben, I've got a 9.8 you can borrow if you can't find one nearer. I've got a Yam 15hp 2 stroke you can have a go with too.
