Members SpfldCoAngler Posted October 18, 2017 Members Posted October 18, 2017 Looking for a knowledgeable Evinrude mechanic. Someone that is familiar with the pre OMC (2000) year model ficht 175 60° V6. I installed a 6" jackplate (1999 Stratos 285 pro elite) boat ran for 17yrs without one and adjusted the engine to 3.5" below pad. The water pressure dropped from 15psi @ 4500rpm before jackplate to 10psi @ 4500rpm (water pump replaced 1.5yrs ago). Dropped the engine to 4" below pad to get better water pressure and water pressure dropped to 10psi. At this point I ran the engine up to 5200rpm to see if the water pressure would go up. After a couple min the the water pressure dropped to around 8psi, temp light and siren came on. I turned off engine to let it cool then returned to dock, ran it up to 4500rpm no light or siren. Engine never went into limp mode. Any help and advice would be greatly appreciated. ( I'm aware that Evinrude had some issues with these engines but replacing the engine because of what it is, is not an option) Thanks.
grizwilson Posted October 18, 2017 Posted October 18, 2017 I am sure Wrench will jump in as he is the Man. My guess is the water pump impeller has gotten brittle and you are having "ears" coming off. But I am calling them ears, so wait for Wrench, but I would change the impeller. If you have a fitch still running you got a good one.....

fishinwrench Posted October 19, 2017 Posted October 19, 2017 When you say 3.5" and 4" "below pad" are you referring to the cav plate ? Surely not!?!? Let's settle that first, but what is water pressure when revved up to about 2500-3000 at idle ? (Don't do it for long.... just a quick rev)
Members SpfldCoAngler Posted October 19, 2017 Author Members Posted October 19, 2017 Wrench, I'm sorry, I miss stated. It is 3.5 - 4" from the prop shaft center point with the pad level and the cavitation plate level. I haven't revved the engine without it in gear. At idle the water pressure doesn't register, but it has a good hard stream out the weep hole ( don't know the real term).
fishinwrench Posted October 19, 2017 Posted October 19, 2017 With a 6" setback I'd expect you to be running with cav plate 2" above the hull on that Stratos. Quite awhile back people started doing their own water pump service, and Marina's with "more important things to do" started throwing water pump service to thier flunkies. On some motors that's fine but on your V6 Evinrude there are a few little special things that need to be done when servicing the water pump.....or else you lose pump volume and pressure, and create excess wear on the lower pump plate. Basically if you don't know what "driveshaft preload" means ... then you have no business servicing the water pump on a 3 cyl, V4 or V6 Evinrude. Anytime water pump pressure is in question the first step is to PROPERLY service the pump. You can't learn the proper way to do it on YouTube. I know because I've watched them all and snickered when they said "and that's all there is to it. . .Thanks for watching and please Subscribe". There is also a service bulletin on 99-2000 Evinrude Ficht's that requires you to re-route the pisser hose. That hose needs to go over the Starboard cylinder head or else you are running with an air pocket in the cooling chamber. Water does not fully fill the block (above the bottom edge of the thermostat) if that hose is below the top of the uppermost cylinder head. A good stream out the indicator (pee) hole shows that some pressure exists in the cooling system but it doesn't indicate anything at all about the volume of water moving through the system. To add to that....dash mounted water pressure guages are flakey, plain and simple, you can take 5 brand new ones and they'll all show different readings.
