^^^^^^ Along with the scoring these pumps are notorious for spitting the shafts out. The Hardin pumps have a larger shaft and bigger bearings and also take the old style (plastic housing) Merc impeller. I went with the pre-installed pulley. Looks sweet and alignment dead-nuts on.

Just a terrible design from the go. NOthing good about them at all. Needs a total redesign from the ground up. Built to fail..

I have found better belt alignment using their pulley already installed rather than pulling the old Merc pulley and reinstalling it. Keep in mind - better belt alignment can add to IAC longevity. Belt dust is an IAC killer.

Like I said the wear plates will wear and can rust.

These next pics are from a one year install by me of the CP / Hardin Pump - their pulley installed and their wear plates kit. The wear plates still groove and need replaced 2 years max or even less including New OEM impeller. Again one year old install and about 90 hours of run time on LAKE TEXOMA. Yes a Lake not salt water running. https://cimg6.ibsrv.net/gimg/www.off...959e39cedd.png

I would use the CP / Hardin housing / pulley / kit rather than Merc set up inwhich is internally soft anyday of the week.

thanks bup, good info,

i'll end up switching to the hardin pump w/ pulley. right now the original sea pump w/o impellor is going on so i can finish plumbing
and rigging the starboard side of the engine. i remember the seapumps on the mark 4 engines being much better. too bad there isn't a retro
upgradeto use the old pumps, (the cool fuel meter could thread right into the back of that pump, or at least the hardin stainless version of it)
what would it take to do it a bracket and a serp pulley ?

I see so many people at the ramps trying to drive their boat up onto the trailer. People with nice boats who should know better, reving the hell out of their engine to get the boat all the way up. In that effort they are kicking up so much mud and silt and debris from the shallow water and it's all going right up the pump. Salt water or not, cut that engine at the ramp ASAP, winch the boat up and save your pump.
