any input: 2.5 & 4hp yamaha 4 stroke for dingy motor. thinking the 4hp could be used as a back up for TONKA (cd.22) i know the 4hp is ninimal . measurments: anchor well bulkhead width at the top, & from the top edge to the underside of the deck. I want to bolt on a light ply panel as a water deflector for the anchor rode. 2nd measurment: height of the moulded in step in the cockpit. from the floor to the top of the step. TONKA is a 2002. any problems with the small yamahas thanks B&R :?: :?:

I've been thinking the same thing -- though I would be concerned that the 4 hp may not have enough power if the main were to fail in a current or wind. I did move Tortuga with a 2.5 this summer in Roche Harbor but if there were a cross wind it would have been -- well exciting. Tohatsu makes a 6 hp which is the same block as the 4 hp and weighs 55 pounds (as compared to Yami's 48 pound 4 hp). With a 15" transom height the small engine would be perfect for a dinghy, and usable on the CD-22 with a retractable motor mount. I don't know that the 20" motor would fit well on the dinghy. I suppose its a trade-off.

Thanks for the info Matt. I like the Yami portables . The 2.5 is approx. 37lbs.& is all i need for the dingy. The light weight will be great for on & off the dingy. The 4hp at more weight (48lbs.) will nove the C-dory better;(in calm conditions) The Yamis have carryhandles fore&aft . The 4 has a remote tank option.
Keeping the main engine tuned & reliable also comes to mind. If you are considering the 6hp Tohatsu take a look at the 6hp Suzuki same weight larger displacment. (size matters)
I still need the measurements ? Can any one HELP? The boat is in the Bahamas & I am in Nova Scotia. BRRR! Thanks . Bill&Ruthe
 
The 2.5 Yamaha is only available as a short shaft motor. This may not be an issue for you, but it was for me.

A couple of comments--I think it makes a lot of sense to use a dinghy motor as a kicker or back up. I do this all of the time--with a 3 hp outboard. My fathers sail boat was about the same dimensions and hull shape as a CD 25 (only weight was probably twice as much) and was easily driven by a 5 hp outboard of 1932 vintage--we took that hundreds of times to Catalina Island--sometimes a bit slow--but we always made it.

The 4 hp should move a 22 close to 4 knots or slightly more in calm water--and that is a lot better than swimming--in a current or wind, it will allow down wind or current to a safe place--agree that modern outboards are rare to fail!

The long shaft can be used in a dinghy but it is a bit more difficult to handle in shoal water--that 5" more draft makes landings a bit more interesting, but I have done it.

Bob, the long shaft only draws more water when used on a dink designed for a short shaft. My Alaska Series transom is mounted on top of the rear tube and thus is spec'd to use a long shaft motor.
