Nice work! You are so right, there isn’t much meat or clearance there.

Uh, maybe remove the gearcase first so the water pump housing and impeller don’t melt?

Mumbles, he is working on a “turbo jet”, no gearcase or rubber impeller used here.

Running nice correct temp now.   Added extra muffler cooling. So now you can even hold the muffler uShape with your hand

As I was giving it a once-over I opened up the turbo jet gear case and thought I would check the oil needless to say I removed about 55 Oz of foamy yellow contaminated oil.. (see pics)

Yikes! Immediately Replaced with new 75w-90 synthetic today.

It topped off at 76ounces of gear oil. Even tho the online capacity stats says 84.6oz

Just change the oil frequently, don’t mess with it.

Sunbird seems to be doing very well.  the current cooling configuration works great.
(additionally I managed to get another project jetboat for virtually nothing so I have some ideas for that)

So just listed it in my area so someone can enjoy it, I don’t go out enough in it.

Seems that because of the supply chain disruptions (which NO-ONE has been given, or has a clear, understanding of why they are happening… we’re all just told to accept it as “a chip problem, or a HR problem. and look the other way.) You cannot get a used jetboat this year.

and furthermore seadoo has stopped making jetboats entirely now. Supposedly Scarab is going to make some I heard?
