sea strainers

dragon

Does anybody know if rinker puts sea strainers in their 320 fiesta vee's?  Boat heats up under way but not at idle.  Replaced impellers.

Should have them. Follow the hoses down to the thru hull fitting

i just had that problem. i hope that's all it is for you. i cleaned my strainer and flushed the raw water system, heat exchanger, power steering fluid cooler, and all seems to be good now. here is a link to my thread with some pictures of the clump of mud i pulled out.

Some do, some don't.  Look for thru-hull fittings with shutoff valves in the engine room between the engines.  If you have them, it means you have dual pickups -- one from the outdrive, and one from the thru-hull fitting and strainer.

If you don't have separate strainers, the culprit could be the water pickup hose from the outdrive.  There's a fitting where the hose comes through the transom.  The fitting can corrode and restrict water flow.  

This happened on one of my 496s, and I had a **** of a time finding the problem.  Look here for details:

Had the same problem on my 342, both water pumps were badly scored and needed replaced.

Al, how much for one of those installed. If ever my pump casing is worn, I'd be looking for a more robust solution.

so far the kit I bought for the brass pump including a wear plate top and bottom with a shorter impeller seems to be working ok......that was 100 bucks. If this does not work I will bite the bullet and get a new Hardin as suggested.

Al, do they have one with the fittings for the manual air pump?  I just bought one new pump with those fittings for approx. 700.  It does have the replaceable plates. I will probably need to replace the other one soon.

Dream!!!!!!!!!!! $700 for a pump but not a prop???

Thanks Al. I'll have to look at it for my other pump. I can't believe the ones with the manual air is almost twice a regular one.
