I saw jet replacement lower units somewhere but don't remember what sizes
they were. At least I can tell you they exist. I'd be a little skeptical
about 40 hp being big enough. Jets take more hp than props to move the same
size boat at the same speed.

I have a new 40 hp Mercury outboard on my 15 ft. aluminum center console.
If I had known the versatility of jet pumps I would have bought one, but
now
having the new boat and motor wonder if it's cost effective, or even
possible to purchase a kit to change my prop motor over to a pump. Anyone
have experience with this?

TIA
