4.3L Mercruiser - works great
Aftermarket parts are meh but this one has been a great find. Three years since I’ve put it on and it’s running like a champ.

Don’t buy
Only ran boat for one hour after installed. Now it craped out. DONT BUY. MADE IN CHINA. I should have known better. You get what you paid for.

Replacement for a Crusader Low Pressure pump
My starboard fuel pump stopped working and I needed one rather quickly and reasonably priced. This fit the need. Easy to install and new O rings are included. So far it works great.

Only ran cumulatively for a couple of hours, but warranty replacement honored
ONE STAR: Pump worked for only about 2 hours. Unfortunately that 2 hours was spread across a few weeks. Having replaced the pump into my boat and then diagnosing a fuel delivery problem a couple weeks later to find it being the new fuel pump was quite a drag. But, of course, it can no longer be returned/ replaced. UPDATE, TWO STARS : Or, so I thought. I have reached out to JMPSPEED regarding the "Warranty" mentioned. They say they are sending out a replacement. We'll see how that goes. UPDATE, FOUR STARS : Received warranty replacement pump and all is well. Just can't go full 5 stars given the initial failure.
