Hi, I have a fun winter project, and have a few questions you smart rotory folks can help me with. The project is my 15' boat I have a jet drive installed and will be driving it with a 13b motor.





I have bought (2) bad 13b motors, picking the best parts from each to make one good motor. Motor #1 rear rotor through an apex and chewed the rotor housing up bad. Motor #2 front rotor through an apex and chewed the rotor housing up bad. the remaining good? rotor housings have this groove in a couple sections.



Question #1. Are these rotor housings reuseable, or are they crap? See next 2 Pictures

Question #2. If they are junk, can I use turbo housings on this non turbo motor without an issue? only difference I notice is exhaust is more open.











Thanks, Joe

Amazing idea! Might want to ask the rotary engine building and porting topic

Those housings are trashed. AFAIK, you'll have no issues using turbo rotor housings with the N/A engine. Everything i have done thus far has been turbo's. Hopefully someone with N/A engine experience speaks up on this issue.



Swweeetttt project BTW.

I love your project! I am a newbie at this site, and it seems to be dedicated to cars.





I too am doing a 13B boat project over the winter. I have a 1972 Mark Twain V-Sonic I/O that originally had a Mercruiser 90. I swapped that out for a 2.5 liter GM powered Mercruiser 120 in 1999. Pretty good performance but I want more, so I am installing a 13B that has been marinized and supercharged, mated to the Mercruiser Alpha I/O. I think the little 15' should scoot around pretty well with it. Should make about 300HP when I am done.



I would love to see the progress on your project!

Well damn you two make me want to do a rotary boat project.

Turbo housings will be a little bit of improvement in power as the exhaust sleeves have less restriction.



S/C Boat looks good!
