Awesome! They look like they'll bolt right up exactly what I was looking for.

Had the boat out last weekend she's running good! It has a 13x21 prop on it and I was only going 40 on gps with 3/4 a tank at 5k rpms wot. From what I'm reading online it should be faster. The prop isn't in the best shape. Would a 14 1/2 X 21 cleaver be too much for a stock 260?

Bigger diameter in the same pitch isnt likely to help your top end. A cleaver style prop will also likely be hard to get on plane as the were not really intended for deep set outdrives. Your best bet might be a Merc Lazer style in a 23 as a next step to try.

They came stock with a 19p cleaver. 21p will work, but will be tough to plane with 4 people and a lot of fuel.

Have had one of these boats in the family since '84 and it is still around and used every summer.

Note sure what modern prop will work better, if it does. The 19p and 21p are still used to this day. 99% of time it has the 19".

So my summer ended with a bad riser locking up my motor. im building a 355 and im trying to find some upgraded manifolds. i was looking at eddie marine thunders but they have a 26" center to center spacing. my thru-hulls are 24" center to center. Is this because its an 86 or what? I cant seem to find any answers searching the inter-webs to death.

A high perf aluminum manifold will likely be wider than the old merc iron anchors as they are designed to flow more.. A muffler shop could bend you up some offsets to allow your downtubes to mate up with the thru hull tips.

I'm going to repower my Scarab 1 with a 410 Ford SB next year and will end up with similar issues. I will be using GM LS manifolds with an adapter.

That's an awesome project. I ended up going with Hardin marines seaward manifolds they are only 7/8 of an inch wider instead of a full 2" of other brands hopefully I'll be able to make it up with the rubber joints

Good job! Hope they work for you.

As for the project, I have everything I need for my new motor except exhaust. Its tougher with a Ford than a Chevrolet, as there are no decent marine manifolds that fit the twisted wedge, TFS 11R Ford heads. Fortunately, the LS shares almost the exact same bore spacing, so IMCO or Hardin manifolds can be adapted to fit.

I'll have one of, if not the only Ford powered Scarab 1 around. I have a blown 509 Chevrolet in my Nordic, but wanted to be different with the Scarab 1.

I saw a couple of these boats with a mini radar arch. Was this an option?? If so does anyone know where to get one?

Thanks!
