Dinghy Motor Replacement Results

We gave up on the 1976 Mercury 2 stroke 9.8 horse motor (with 12 horse jets and reed valves)

Replaced with a Yamaha 2 cylinder 2 stroke 8 horse motor in new condition.

It weighs only 60 lbs.

The Yamaha 8 takes our 10.5’ high pressure air floor dinghy to 15 kts/17.3 MPH with two adults on board.

Planes effortlessly at 10 kts.

Once we repair/replace the somewhat rough edged prop we should do a bit better.

The Yamaha starts on the first pull, uses 100:1 fuel oil mix compared to 50:1 on the Merc resulting in less smoke, is much quieter, what a difference in noise plus the nearly all the exhaust flows out through the prop.

The biggest surprise is that the published weight difference is negligible at 4 pounds, however with the large built in handle at the front it is far easier to heft on/off the dink and back to the garage where it will receive a new impeller shortly.

Maybe it’s a bit more compact than the gangly old Merc.

Thank y’all for your input on this one. I am really glad I passed on the 90 pound 9.9 Yamaha.

That 60 lb Yamaha 8 will be a breeze to stow in the lazarette and I can still use the St Croix mini crane if I need to/want to when I become an even older fart.

+1 My wife has my Christmas list (new bilge pump, etc.). She knows, however, that whatever I don't get for Christmas I'll buy myself in January. It's nice not being a kid!
