Contemplating buying a '86 22' DONZI, boat has SBC w/ Alpha. Have a spare 300X in garage. I know the Harbormaster bought the ONLY 22 O/B made, and converted it to I/O, was told boat didn't perform good. But, I belive the motor was mounted on the transom. I would put motor on a bracket & use the engine comp. as storage. If set up properly I feel this could be a worthwile project. Motor would be a 20" w/ Sportmaster lower, weighing 444#. Has anyone tried O/B on a 22? Your comments ? "HIGH LIFE"

Here is my .02 ......

Harbormaster should never have done that to a 1 of 1 factory authentic OB and you shouldn't reverse an IO either.

Harbormaster acquired that boat From Woodsy on Winnipesaukee . . he's not active here of late, but you can find him on Winni Forums

Woodsy had a nice BBC yellow 22 before the OB 22 . . and there's comments on that boat in Donzi.net . .

going on memory...

HM's boat was originally ordered as a single OB bracket, then changed b4 production to a twin Armstrong bracket setup, with twin Yammi's...

I don't see any way a 20" engine is going to work without it being submerged coming off plane, most std. brackets are 16" setback

Not factory but well done.

A 20" would be tight on that hull, and you would need at least 18" of setback to trim it up. All this leads to a Porta Bracket and a 25" leg which is easily gotten in the 300X as High Life already knows. You could go 25" leg, but my question is why do it? Go find a factory OB Cig 21 or the like?

CDMA, where did you see that rig? Looks like they splashwelled and then shortened the doghouse.

Made a typing mistake, 300X has a 25" mid. A lot of boaters complain about storage on their boats so if I keep the engine hatch and install a floor on top of stringers I would have plenty of room. A porta bracket would be the most versitle bracket with high lift, also I firmly believe the prop shaft should be run even with boat bottom, devoloping more forward thrust. A 18" set-back would be a good starting point. I'm looking at this project as a h.p. to weight experiment. "HIGH LIFE"

That picture was taken at the Abaco Beach Resort in the Bahamas,I live right down the street.I can't say I've ever seen that boat before.

Allright HIGHLIFE, I told you to lay low with the weedeaters on this site, but if you insist on a 22 conversion here is the list I'd like to see LOL

1. Open the bow like Carl C
2. Add a pad like Greg G
3. Increase the tank size like Parnell
4. Full side steering for that X or yours
5. Call Scott Porta for the custom Porta-Bracket
6. And of course, the first step......hardcore transom changeover. pic attached to help you out

I expect you to post up in the 2011 Fastest Classic thread with that bad boy :cool::pimp::lightning

Correct on the Abaco Beach Resort.

I found it particularly interesting as I think doing a motor well and not a bracket is the right way to do a 22 Outboard. While the bracket would undoubtedly be faster you would inheretly be chasing handling issues because of the screwy CG. While the handling issues could be worked out in calm water a properly balanced boat is key for rough water comfort and handling.

As it is a 22 with the BBC is poorly balanced. The best running rough water 22's are the SBC / Alpha ones.

It looked to me in this case they just cut into the transom and made a motor well out of the engine compartment (or part of it). The glass work was fair, not perfect. But I liked how they did it.

High Life would need to get the donor 22 up on the sling to see where the C/G is currently fully rigged
