Holy crap. Has anyone pulled the oil coolers from behind the motors of HP500's in a 36OL? After many hours of working them out, I finally was able to clean all the old impellers out of them. I will never ever dry fire my boat again. Lesson learned! Oh and Scott I found the trailer paper work.

Great fun huh?! I've had to do it a couple of times. Parking on the beach like you are doing in your avatar doesn't help the impellers either. They will suck up sand from alot further down than you think.

Just reverse flush them instead of taking them out

That will only work on the small pieces. The last time mine went, it sheared long pieces that wedged themselves in the coolers sideways. I had to use side cutters to get them out.

Define dry firing a boat...because a split second with no water can ruin a sea water pump.

They do have those blue ones in the swap shop that are supposed to take a split second or so. When you first put your boat in the water. The pump is not primed.

I have been very lucky with over 700 total hours on three Baja's with a lot of coastal trips to have never lost an impellar.

NEVER dry fire an engine with the belt on the pump, and ALWAYS change your impellar and housing at the beginning of every season.

It works for me.

That's about it. There are a lot of guys who wish they could get that kind of reliability.

It is if the pump is below the waterline where you back your boat into...there is water right there against the impeller and some flowing by before you ever hit the starter...trust me

I back into the sandbar.But the motors are not running, never had a prob
