A good spec. Roy is a little anti A frames, I think the boat would benefit aestthetically for having one. What top speed is it achieving with the HO and which prop is it running?

I agree about the a frame, and this is a seperate point that I will seek advise about in the next couple of days re nav lights etc. Its spinning a 22" Viper possible 15 1/2dia but im not sure about the dia. In the previous post where I said I was putting an offer in, it was on a solent 6.5 with a 200ho (he wanted too much, and it fe;ll thru) and that had a 4 blade rebel and that acheived 65knots!! In the SB&R article it quotes 57mph@5.2krevs but it now revs to 5.8k so i dont know the speed now! Do you think it would benefit from a 4 blade? I know it wouldn't increase WOT but would it benefit economy! It burns 100l+ flat out

The best I've had out of mine is 49.1knts running a 4 blade. The Solent is considerably lighter than a Vipermax.

Well with 25hp extra, I should be able to make 52/3? Do you think it would benefit from a 4 blader?

Quite a list of things that I want fixed/added/done etc. so I hope maybe complete b4 ~20th december (Have to find a cheap date to stick it on the ferry)

I think Roy was getting around 50 knots out of it however I know he tried a couple of different props. If you fit a 4 blade prop you will probably losse some top end speed but gain holeshot, I would stick with the Viper it is the best all rounder IMO.

The Ideal RPM for this motor at WOT is 5600 so you are probably pretty close to ideal propping, You could try a 23" pitch viper or perhaps a Raker if you wanted to wring out every last knot.

Be careful with those trim tabs you could have the first Osprey Submarine if you get carried away

Strange, when looking at the thread it says "try a 22" Viper" but when it comes up in the reply page when I quote it says 23"? I assume you mean 23 'cos its already got a 22! I imagine I'll leave it as it is though.
