Fleetwin,
Just listed that boat setup for sale and had a guy start emailing me about the engine swap. he seems totally convinced that this engine swap cannot work (the way it is working, btw) the donor 140hp motor is a 1978, or in any other case he basically claims the setup is just going to “poof” at any time.
He’s key points he’s using: “In 1991 The V4 crossflow crankshafts changed in 1991 so if you have a earlier engine than a 91 the splines on the crank are not a exact match to the jet drive.”
– on this: if true, I cannot see how the engine would have installed at all??
And ” Your cooling system has not been modified for the Turbo Jet set up , the Turbo Jets had cooling problems from the factory add some sand and poof goes the motor . Very
important when swapping a outboard engine to the jet drive .”
– on this: I’ve been monitoring the temp and it seems to run nice and within bounds. the temp warning sensors are all in place, just in case. the only difference I can see is the little 1/8″ NPT air tubes on the top of the cylinder heads…
