    1989 Evinrude 88 SPL (E88MSLCER) Exhaust Housing Leaking???

    Notching the valves and reaming the air escape hole seems to have worked. Ran the motor on the hose both heads settled in at 145(p)-150(s) with 20 minute runtime, with no overheat alarm. Temp cycled with t-stats on both and t-stats housing reflected head temps so gonna conclude that this issue...

    1989 Evinrude 88 SPL (E88MSLCER) Exhaust Housing Leaking???

    So, got the thermostat housing out, once again bit in the ass for not knowing to look for the hole in the slot to void the air. It was of course plugged with salt and that entire slot was filled with gasket seal when I first took it out months ago. Not knowing I didn't really attempt to...

    Got this on the iboats forum: Anyone else heard of this? these can develop an air bubble in the t stat housing, keeping the t stats closed or barely seated and not fully open. there is a notch to be made in the poppet valves to stop this happening. get it in the water and let it warm up to at...

    1989 Evinrude 88 SPL (E88MSLCER) Exhaust Housing Leaking???

    OK, all seals, gaskets, grommets replaced, leak fixed... Pump seems very strong telltale the most I've ever seen from it. test 1 Started with both hoses left off, both heads running strong flow of water. Put hoses on started motor. Temp slowly increased on both to 121 all seemed good Then...

    1989 Evinrude 88 SPL (E88MSLCER) Exhaust Housing Leaking???

    I was reading the procedure for removing the exhaust adapter... another issue/question comes up.... While looking on the site for the parts to do the job (gaskets for the housing bottom etc. that I am inspecting), my motor has a gasket on the upper mount cover. I can find no such gasket on...

    1989 88 SPL (E88MSLCER) Power Head Torque

    Thanks... Yeah I recently bought the original service manual for the motor and follow it exactly step by step. The SELOC I had was utterly useless for this motor

    1989 Evinrude 88 SPL (E88MSLCER) Exhaust Housing Leaking???

    Upon i Upon inspecting the gasket, the hole is the same size as the channel and would likely centers on it, so that big area of pitting corrosion and gasket sealer is an area that should never be wet (according to the new gasket), so the gasket has failed in the past or had a larger opening...

    1989 Evinrude 88 SPL (E88MSLCER) Exhaust Housing Leaking???

    I forgot to add the close up of the base to weep channel, there is definitely a deep gouge from corrosion going to the gasket, that is no longer filled with the gasket sealant

    1989 Evinrude 88 SPL (E88MSLCER) Exhaust Housing Leaking???

    For anyone following I completed the live water tests to see what exactly was going on with the water not shown in the water flow diagram. Exhaust housing, water fed to copper tube under hose pressure... Only water from the square feed on the housing, thumb over feed no leaks anywhere. Neither...

    1989 Evinrude 88 SPL (E88MSLCER) Exhaust Housing Leaking???

    ok so the leak got worse and very little was getting to the heads unless I removed the hoses by the end. So I pulled the motor again to carefully inspect everything. Gasket was fine no parts missing that I could tell. Back flushing the motor at the heads, water comes out the single hole...

    1989 Evinrude 88 SPL (E88MSLCER) Exhaust Housing Leaking???

    So, I did a barrel run today after re-installing the lower unit and re-torqueing the heads to get the idle set at 900 RPM. Idles smooth and is very steady, ran it for about 30-40 minutes. Still got water coming out the front into the cup area. No overheat alarm triggered. The temperatures on...

    Thank you for trying... It is a bizzare issue, doesn't make any sense how water is getting there.

    1989 Evinrude 88 SPL (E88MSLCER) Exhaust Housing Leaking???

    I Forgot to mention: I found while running a tap through all the holes for the heads, to clean them up, that bolt hole #7 on the port side of the block was cross threaded, as bad as I have ever seen, so that's why I had to pull the motor- to drill and tap for repair with a Heli-Coils. I had a...

    1989 Evinrude 88 SPL (E88MSLCER) Exhaust Housing Leaking???

    Thank you very much for the help... I had replaced the entire pump this spring, I think the turbulent removal of the motor may have dislodged or broken something. The motor was salted in bad all screws caked and the base gasket had been leaking at some point freezing the motor and base with...

    1989 Evinrude 88 SPL (E88MSLCER) Exhaust Housing Leaking???

    I put in a totally new water pump in the spring. Would pulling the motor have affected it in some way?

    1989 Evinrude 88 SPL (E88MSLCER) Exhaust Housing Leaking???

    New day new problem I think... Both Heads completely descaled. Both head gaskets replaced and heads torqued to 20 ft/lbs on the bench. I have not retorqued the heads yet after the run gonna wait till morning. I installed the motor to the outboard exhaust housing, torqued everything to spec... I...

    1989 Evinrude 88 SPL (E88MSLCER) Power Head Check Valves

    I'm debating whether to go ahead and order 2 more check valves and replace all 4. It seems they are responsible for 2 very important things in lubrication to bearings and keeping excess fuel building up... Am I over thinking things?

    1989 Evinrude 88 SPL (E88MSLCER) Power Head Check Valves

    Lesson learned about putting fuel lines into a sealed plastic bag... I honestly thought they were vacuum lines... The line should have been marked B/W (line color)[ One Dot)] according to my motor... the Starboard bypass 1 line the other bypass (only surviving mark) 3 lines.

    1989 Evinrude 88 SPL (E88MSLCER) Power Head Check Valves

    Thanks for the info, I just purchased the original service manual from Ken cooks site. The seloc has been utterly useless for everything I have tried to do thus far.
