I Have a Toasted 175 XR2 Sport Jet In a Regal 1700. The boat is in good condition Engine is Junk.
2 Cylinders destroyed,
4 Con Rods
6 Pistons
Crankshaft Gone.
Hole in Crank Case.
To name but a few problems.

I'm In England so parts for these motors are none existant.

A freind of mine who has a machine shop races NS2000-F2 Power boats with 2 litre XR2 2 stroke engines, tuned to 200 hp he's suggested using one of his engines and converting it to run on the jet pump.

He's suggested machining the end of a standard merc drive shaft (8 spline) onto the end of the sport jet drive shaft (13 spline) to enable me to use the standard V6 crank rather than a replacement expensive sport jet crank.

Question is has anyone ever tried this aproach ??

<!-- loop replys -->The casting s on the 2.0 ltre race engine are almost identical to the 2.5 sport jet<!-- /reply loop --></TBODY><!-- /onionskins -->
