Decent older paint job, cleans up ok.

Haven’t gps’d it but it gets there. If it doesn’t do 60 it’s not far from it.

Full disclosure:

Bottom of hull has utilitarian features consistent with ~35 year hull.

Front motor mounts are through bolted/glassed in. Battery box relocated with aluminum plate and one bugle headed through bolt.

I like the handling provided by Tom’s front sponsons but they’re scratched up, one side has been partially broken and caulked back together. Can’t tell when riding just looks like a temp repair turned permanent.

Could use a defoam or add hull drains. Turf is in good shape but looks like it was rushed.

Stripped threads/missing m10 on one of the bolts for the engine lift eye. Plenty of other bolts for support never saw as an issue.

Asking $3800

Located near Lake Norman NC

Very cool swap. I’ve always wanted to build an SN with a triple.

Did you use the OEM sn exhaust tube?

Thanks, I cannot take credit for the original swap. I've only went back through it all when I did the rebuild and made minor improvements such as clearance and rub prevention. Exhaust is compiled of a 120+ degree exhaust elbow coming off the stock exhaust and into a system of modified intercooler piping from a 2nd gen power stroke, through an unknown brand water box and into a 3" PVC thru hull pipe.

Save you a lot of busy work to come get this one vs building from scratch

I have some video on an action cam but never uploaded. Previous owner allegedly GPS'd 57 on a tired motor, but I have never verified.

The mag pump, impeller and bored nozzle all seem to play well together. It gets close to top speed very quickly and I've never wished for either more acceleration or top speed. I'm sure with more pitch it'll go faster on top but it is already approaching novelty speeds.
