Author Topic:   Outrage 22 Transom and Splashwell Modification

I'm looking for photos of Outrage 22's with the pre-1989 basin-style [sink-style] splash well, which have been modified to reduce the problem with [wet decks due to water coming over the low transom]. The best idea I've read about so far is raising the transom to 30-inches. Has anyone in this group done this?

Perhaps there are some other good solutions.

If you raised the transom of a notched-transom Boston Whaler OUTRAGE 22 so it was appropriate for outboard engines with 30-inch shaft length, I'd see two problems:

--finding engines with 30-inch shaft to use on the boat for single engine power; I don't think 30-inch shaft engines are very common these days, particularly in the horsepower range appropriate for an OUTRAGE 22, about 200 to perhaps 250-HP. I suppose you could get one, but you'd probably have to special order it. If you were looking for twin engines, say in the 90-HP to 125-HP range, you'd be fine, as they'd need to be 25-inch shafts. It might actually help with twins, as counter rotating engines with 25-inch shafts are more common than 20-inch shaft engines.

--restricting the flow of water out of the boat via the low transom; if the cockpit were ever to be swamped with a lot of water, as might happen if a big wave comes aboard, draining the water out of the boat over the transom is going to be significantly slower with the raised transom. You might think it could never happen to you, but then it could--who knows when you might be out in some nasty conditions. I'd rather get some wet feet than an extra six-inches of water in the cockpit.

You could alway cut two large scuppers into the transom and put flapper valves on the outboard end.

I think the simplest solution is just to install lee boards or transom boards on the transom, on either side of the engine (assuming a single engine boat). The transom boards would cut down on the amount of water getting over the transom, and they'd be much simpler to install than to raise the entire transom six-inches.

Most manufacturers offer their 200-HP [or higher] outboards with 30-inch (XXL) shaft length, so this isn't a deal breaker. There is also a manufacturer in Ohio who offer extension kits for all engine brands except Suzuki, so one could convert a small block 150 to 200-HP 25-inch-shaft engine to 30-inch-shaft. Warranty from the engine manufacturer would likely be affected.

I think twins would use 25-inch-shafts, so that would be easy.

As for water egress in a swamping situation, it would still escape much easier than in a full transom Outrage 22.

I understand that some commercial hulls had a 30-inch-transom option.

I'm hoping someone has completed this project, and might have some photos to share.

I have seen some boats that fill in the engine well with foam then glass it over just high enough to not interfere with the engine bolts. This would keep less water in the boat, but not prevent new water from coming in. I do like the idea of a board across on either side of the engine and have considered that for my boat ('79 Outrage 22).

When I had my [OUTRAGE 22], I made 12-inch-high fillers for the transom out of 1/2-inch plexiglas and used 3/4-inch by 3/4-inch aluminum C-channel to hold them in place. [These fillers] can be removed if running in heavy seas where you would take waves over the bow. I also foamed and glassed-in the deep well and made it into a normal splash well, somewhat shallow but worked well. Last, I had a 28-gallon aluminum tank fabricated that I stuck in the fishwell and sealed it in. No more water collection devices.

Instead of raising the transom, why not modify the splashwell to mimic the 1989 and later era boats, which have a full width splashwell dam that is still low enough to shed water over the transom if needed? The decks stay dry and any water that comes over the transom quickly drains out of the oversize transom drain tubes. IMG_0187.jpg

I've thought about your suggestion Andy, and it may turn out to be the way to go, as my preferred engine choices are not available in 30-inch-shaft.

I liked the idea of a 30-inch [transom height] as it would resolve both the water ingress problem as well as retain maximum useable floor space. I don't think the more difficult water exit would be a big concern, as getting most of the water out would resolve an emergency anyways.

The add-on "fillers" would work, be super easy to do, but would look like add-on's, and I'd like a more tidy look.

I have a 13 whaler with the same concern, and subsequently used 1" whiteboard. (yes, used for exterior siding or decks) to design filler panels for both sides. Although it doesn't look original, either would a more expensive fiberglass complete transom. I get a lot of positive feedback from those, like yourself who have experienced gallons of water at the helm from following seas or backing up for whatever reason. Just a thought !!
