Request: Yamaha 9.9 vs Honda 15

Asking for guidance here please.

The build of our Cat suggests to Yamaha 9.9's. We are looking for electric start and tilt a bonus, both available with the Honda. The motors will be left on their engine pods and used only in a saltwater environment and we require long shaft, 4 stroke.

Given this and corrosion technology to date, could I please get some feedback on one or the other, do's and don'ts, stay-away-from..., corrosion issues, development changes, reliability, in fact anything to try and make this decision a little easier.

Thanking you in advance

Can't tell you about the Honda, but I have 2 Yamaha 9.9, 4-stroke high thrust engines. The important thing about the Yamaha is the 3:1 reduction gear transmission, that develops the high torque for the 11 3/4" prop. I think the Honda has a 2:1 gear, and a much smaller prop. Most sailboats need the slower turning, higher touque at the prop.

Thank you for your help. Some other details I have located include:
Quote:
Honda BF15 Yamaha 9.9HT
Weight (H) 52 kg (Y) 51kg
Transom height (H) 703mm (Y) 635mm
Gear ratio (H) 2.08 (Y) 2.92
Prop size (H) 11 3/4" (Y) 10.5”

Difference between the Honda 15 and the 20 is just the carburettor.

A 9.9hp flat out and using the fuel that goes along with WOT (wide open throttle) is making 9.9hp.

A 15hp will make the same hp, and a lot more torque at much less throttle and would use much the same or even less fuel, but on WOT will return a knot or two more speed. One gets power tilt and an extra 4 amps charge, at a price.
I would be interested in the reliability (specifically the later models of both) and any corrosion statistics from anyone. Thank you again.

The Honda BF20 is not much bigger than the 15HP, and has power tilt and start. Also has a 12 Amp alternator, which isn't too bad for a small outboard. It is what I have on my trimaran...and it works quite well.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
