I know that most people add a bracket when converting to an outboard, effectively lengthening the hull, but I'm looking at going the other direction.

I need a boat to fit a 22' max LOA slip.

Any input on cutting 12-18" out of the hull just forward of the transom, then notching the transom for an outboard? This would reduce the hull length to the 19-19.5' range. Would the boat still handle ok? Would a Suzuki 140 be enough power?

    Sounds like an interesting project. Do it and post it up so we can follow along. 140hp sounds light to me, when I had mine weighed it came in over 4k lbs.

    Was that 4k lbs with an i/o setup? This old brochure lists an approximate weight of 3200 lbs with i/o.

    Does anyone have an accurate measurement for overall length of a standard 20 including the i/o tilted all the way down?

    Boat builder Lupe Diaz down here in Los Barrilles bought my dead 20ft Skippy and did just what you are talking about. Its for sale up the street so ill see if I can get some pics next time by.

    Thanks, that would be great! I would definitely be interested in buying a boat that's already done. I've got cash in hand, ready to make a deal.

    It most likely be a lot cheaper to just find a boat that's fits the slip you have or are going to have... Modifying that boat will cost to more that what you budget as lots of unforeseen things will nickel and dime you... than the time factor.. its gonna take a bunch of time.. the complete the project as well...
    either way good luck....

    Here’s a picture of my 1970/20 Skipjack 20 Open aka “Black Jack” which has a 200 HP Suzuki, 9.9 HP kickers sitting on an old school Armstrong Nautical (non-flotation) bracket and 40 gallons of fuel. Fully locked and loaded she’s pushing 5,000 lbs.

    More than likely you will have to beef up the transom. Right now the engine is bolted to the stringers. That is where the stress is located. When you add an outboard, the stress is transferred to the transom. The original engineers did not beef up the transome because it was not necessary. Do a lot of research but it can be done.
