Hi Richard,
Simple question I have a 2008 Yamaha 250 will this prop fit and if it does, what does it do differently to the original Black one thats fitted at present.

Cheers
Gary

19" pitch will be slow on a 7m I would have thought unless you are intending to be towing. I seem to recall that these engines have a slightly slower gearbox than other manufacturers so you need a greater pitch.

You need to read off the info on the prop you have to see whether it will be better or worse. The bigger engines don't come with a standard prop - they are normally an optional extra although round about then Yam threw in a prop of your choice from the black alloy range + rigging.

Mine was delivered with a 21" pitch black alloy one but it was overrevving. Since I wanted max speed I upped the pitch to a 23" P x 14.2" D aluminium Solas to play with which was fine so I then bought the Yamaha ported stainless 23"P x 14.5"D one based on the trials that were done on a 7m RIB(mentioned somewhere here on Ribnet).

With one to six people on board + 300 l fuel it maxes out around 5500 rpm which seems about perfect. Flat water and just me its hitting 46 knots (used to do 48 but the A-frame seems to be slowing it down (or I'm getting heavier).

Hi Gary,
I guess your 2008 Yamaha 250 is a 4-stroke? I don't know if the splines are the same size on this series or not. If your current prop is the correct size and you're getting close on max revs at top speed, then there's nothng extra this prop would do for you. The Yamaha Black Steel props are excellent and the Solas ones are no better in my opinion. If you believe you haven't got the correct prop and want to try a different size, then this is cheap way of doing that without investing up to £1000 in a selection of different sized props. Richard Selman's advice above is spot in imho.

Thanks guys for an insight into the black art of Propellers!!

If I am being honest the Std Prop on my 7.5 m Rib is fine, I just fancied a nice shiny one!!

Am I being Vain??
