1988 Force 50 seals

[upsidedownfish]

Model 507Y8C - Overheat alarm went on. The grease in the lower unit was contaminated with water. Should I replace the waterpump kit and gearcase seals? ~$40 vs $12. Any manual pages available showing schematics? Any ideas welcome.

The water in the lower unit didn't cause the hi-temp horn to sound. Get a manual for tha thang and replace the water pump while repairing the l/u.<br /><br />c/6<br /><br />Hooty

Hooty,<br /><br />Already ordered all the parts. The impeller and unit looked good. Did have some sand sucked in and blended with the grease/oil. It was THICK!

What is the best manual available FAST! I bought the boat used - NO DOCUMENTS. Where else could the cooling system be blocked/damaged/contaminated????<br /><br />The boat is a 17' BlueFin and only goes 20 MPH with new prop and stabilizer (stingray). Is this what should be expected? It sucks fuel FAST!

You have a seal failure, so order a complet seal kit.<br />Seeing how you have SAND in the l/u, I would go out on a limb,and say main propshaft seal. But you will want to install new seals all around.<br />Also, if the impeller is older than one year,cjange it while you are in there. Impellers look perfect in every way...Until they fail.<br />For further assistance, click the link,<br /> Everything you wanted to know about lower units and seal failure.

NAPA auto parts has after market service manuals.<br /> Also listed at the bottom of this page,amazon.com<br />area bookstores,ebay etc.<br /> If there is sand in the lower unit there may sand<br />in the cooling system.May be a good idea to open it up and look around.<br /> I would guess your boat would run about 30mph<br />with one person on board.<br />Check to see if you are running on all cylinders.<br />Do a compression check.<br />If it was mine I wouldnt put to much money into it unless you really love it.<br />The Force is an orphan and is pretty low on the list as far as performance,reliability,and resale value.<br />Some folks swear by them and others swear at them.
