Will my 13-ft Boston Whaler keep the motor dry when it swamps (and other Qs)

We were dealers for Boston Whailer in 1972, so I know your boat. The transum was for a short shaft, an in those days the 40HP was the recommended motor. I have personally been in the Cheasapeke Bay in a swamped 13 ft whaler with a 40 short shaft. in 5 to 7 ft swells. The motor would not only start and run,(power head out of water), but it actually caused water to self bail over the transum, and then it drained through the drain hole until almost all of it was out. I agree the spacer was to use the more common long shaft motor. Height and bracket isn't as important as the depth of the drive (prop) and angle to the bottom of the boat. I could run 3 - 4 hours on a 6 gal tank, but I wasn't full throttle much and not pulling skiers. I hope his info helps. BOL

I've seen numerous web pages that claim that it will keep the power head dry, and some that even say you can leave the drain plug uninstalled (but I'm not sure if the latter applies to with-engine or not).

One note: The transom has a 1/8" stainless plate installed (non-watertightly) on the inner...

Best check out the whaler if an old 1 as there foam filled and have issue with holding water inside the hull and making it quite heavy and performing terrible. They also have a trim built into the hull that makes it bow down when running. The 4 stroke is nice but very heavy for this small boat.With limited free board fair weather and little wind before venturing out. There are other V hulls that won't pound U to pieces for less $$.Have had most all.Take 1 out in a small chop and U will see the hard wet ride.

Boston whaler are foam filed glass lined> Your transon already has issues > raising it 5" weaken the trans> I had a 50hp with a jack plate on mine > It won't sink per say but when full of water it will turn over so the engine will be inverted> Also there is a hook in the last 20" of the bottom> It's called a hull speed> so that much HP will only plow the water with trim it will porpose> I glassed mine flat> And it ran 50 MPH> And could Pull 2 skiers>

It will float full of water upright and with engine block several inches above the water. I have had mine full of water and was able to pull the plug and drain it with 3 adults on board. These boats are amazing.

Also you can leave the drain plug out when leaving the boat in the water so it will not fill up from rain. Some water will come in from outside but it stops. When you are ready to use the boat again you will have to bail out maybe 2 gallons of water or just leave the plug out while you are running and it will drain out.

My Whaler was a 1966 with a 1986 25hp Evinrude. I could get 10mpg at cruise by myself. The 40 Force will probably get 6-8 mpg.
