hello all,
I have a 22 foot sailyboat (ETAP 22, 1.5t, 18' 5" LWL, max hull speed around 6 1/2 knots), and have just I bought a new Yamaha 9.9 4-stroke since the old (1990) one died recently.
I want to put a Dual Thrust prop on it, but can't find reference anywhere to which specific Dual Thrust props are recommended for this engine by Yamaha.
The engine is a F9.9F LMH (i.e. NOT the high thrust engine)
I can find info about F9.9A, F9.9B, F9.9C,
eg,

but nothing about an F9.9F (well, i found this:
http://www.boats-parts.co.uk/index.p...roducts_id=294
but as it's from a parts supplier and not Yamaha, am not sure)
The old engine had a 11 3/4 x 9 1/4, but I would prefer a smaller diameter if possible (to reduce drag when sailing, but mostly so that I can take the motor out of the well in the cockpit without diving in and taking the prop off which is too big to pull up through the well opening)
Anybody offer any info on this please?
I did try to contact a few yamaha dealers, but nothing conclusive and I cant get the dealer search function to work on the UK Yamaha website)
Thanks in advance
