   Hi,

Where to find gear ratio for 4JH3E and SD-40? I think that should be in some "sign" in the engine or sail drive, but that's not the case.

Does someone know what it is?
Is SD-40 common sail drive for the 4JH3E? 

Thanks for the information,
Tarmo

	you can download the specifications here http://www.yanmarmarine.com/uploads/products/pdf/JH/3JH4E_TechData.pdf but i'm surprised you have the 40hp 4JH3, because on all 411's it was first the volvo 55hp, and finally the yanmar 4JH4 the last 2 or 3 years. didn't know a 40HP was an option. as for sail drives, i have SD50 , http://www.yanmarmarine.com/uploads/products/pdf_saildrive.html

	Hi folks The Yanmar 4JH3 with a SD-40 installed on the 411 2004 is rated 56 HP @ 3800 RPM. Not 40 HP which is the 4JH4. Thanks Alex Danciger

	Hiya, Same boat same gear ratio as Alex indicated above; agree his numbers. If you were to buy a kiwi prop, the distributor will be able to match your prop to your boat without any probs. I have had a kiwi prop on our yacht, full-time liveaboard cruising for the last two years without any probs at all. I acknowledge the earlier comments about manouevrability but I reckon in comparison with other folding/feathering props I have used in the past, the kiwiprop is certainly up there with the best of them. At around half the price I reckon the value for money is obvious, you do however need to be religious about your annual haul out maintenance and spent the extra time on the recommended greasing routines. I also like to dive on mine to ensure that it is moving freely and in the correct sense about once a quarter. You should be cleaning the intake ports on your saildrive about that frequently anyway. It is perhaps worth observing that all hull and propellor combinations have their unique handling characteristics; it seems to me that if you learn to use these to your advantage rather than fighting against them you will seldom have any problems. Not sure where the kiwiprop copped the bad press; as I said, value for money, can't beat 'em. Regards Chris G H411 "Equinox" Australia
