Another I/O to outboard conversion...

[Part-time]

It's a 1976 Starcraft bowrider that had an OMC stringer drive.
I'll be building a bracket to hang the motor out back similar to what WeldZilla did for his.
I found a 200hp extra long shaft black max with a blown powerhead that I'll be rebuilding as well.

The often talked about and rarely completed IO to OB conversion you say?

Cool!!! Looking forward to seeing it happen

You found yourself a sweet ride there! You sure you don't want to keep that Stringer Drive? Looks like she's in great shape in the photos there

Rock on!

I'll be the first to admit that I'm no expert on large outboards & inboard outboards (I'm a straight inboard guy for anything 16' & up), but would you really want to hang a 200hp outboard off the transom of that boat? It seems like a lot of weight on a light boat to me.

A 200 sounds like a bit much for that hull,.........

What is the hull rated for??

Re: Another I/O to outboard conversion...

Because it was an I/O there is no hp rating. I would be curious to know what the outboard version of this boat was rated for.
I'm not just going to slap a box on the back without re-enforcing the transom first. It will have knee braces running from the transom down to the stringers opposite of where the mount will be bolted to the outside as well.
As for weight... I'm probably ditching somewhere around 300 lbs by going with the outboard.
I really don't think a 200 will give me any isues, my bosses 20' mirrocraft has a 225 4 stroke yamaha and a 15 hp 4 stroke kicker on the transom.

That's the one good thing these Stringer Drives leave behind, two big fat alum stringers. With a little fab work you can make that transom bomber strong!
