I can't see the photos where I am, (yet) but it sounds like a good idea. I think you should try to source a two-stroke 5hp engine. The weight would be comparable, and you'll have more HP.

If you coordinate with winds and currents, hopefully this can get you through those narrow, unsailable areas of the ICW. I'm glad you came up with some kind of emergency propulsion.

NOT that it does not take HP to move a boat BUT IMHP I think there is a massive misunderstanding of just how bad a standard prop is

Because 4HP moved the 8000# Cal 29 at 4.5 knots and while the now healthy A4 will go 6.5 + the stern sinks above 5.5 knots


The biggect issue was NOT sinking the motor while crossing some BIG barge wakes in NYC

They use pretty much the same system on Jboats Up to the J29 MHOB

If a dirty bottom slows you down what do you think it does to your boat

Chris,

Wondering what effect taking out maybe 300 to 400 pounds from way down low and adding 50 or so pounds way back and up high might have on the sailing characteristics of your boat? Maybe making it a bit tender? Seems like a big change in the overall design function? If you can find someone that has made the same change it would be interesting.

The void where the engine was, probably will not remain empty. He'll load it with gear which will probably offset the missing weight somewhat.

Now that I'm home, the gear looks solid, and well-made. I really encourage you to look for a 5 - 8 hp TWO-STROKE outboard. It'll be very light and give you a better push against an adverse current. If you're going for a 4-stroke engine, then yeah, 4hp is probably your weight limit.

Chris, that's a good idea... but like most, it's not new. We had a boat built in 1982 with exactly that setup - a 24 foot dayracer that raced one-design with the motor below on the cabin sole. We had the exact same type of bracket that accepted the more standard lighter duty spring loaded OB bracket.

We left the motor on the bracket and lifted the whole assembly off the slider just as you plan to do.. there was a keeper pin to prevent the motor/mount from 'hopping' off the transom on a big wave.

Nevertheless, good thinking, and nice work - should work fine!

Seems like an uncharacteristically pragmatic way of dealing with having no engine; carrying an engine for use 'as needed'.
I also must agree that the looks of an outboard hanging off your pretty stern overhang is anathema.
Your bracket bracket looks pretty solid too. Time will tell. If it works then you can patent it and see if it helps your cruising kitty.
For those that asked, I believe that CnC has a 30' S&S sloop, IIRC. Nice looking boat and he has really spared few details with his re-fit.
It is going to be along winter so as far as I'm concerned you can make baiting comments all winter long but in the spring you better be heading somewhere.

Looks great!!

Watch out for bigger seas, where the prop might come out of the water (or the engine get submerged).

Chris,

OK, so noted, 50 extra gallons or so should hold you for a day or two. As said earlier a small motor is better than no motor. Hope it all works out as planned, keep us posted.

Thanks! You wouldn't happen to have any pics would you? I'd love to see another design on this idea.
