    Oil alarm triggers at low RPM

    Good morning. I have a 1985 Mercury 175HP Black Max which seems to run flawlessly. The only trouble I'm having with it is that the oil alarm is on at idle. As soon as I get over 950 RPM, the alarm goes silent and all is good. I've ran through all of the checks I can find in the service...

    Interesting Problem (Fuel?)

    '89 Evinrude 175 Crossflow My 175hp feels like it is taking off in fourth gear. It will eventually plane out and run at around 4800 RPM at WOT but not at the 5500 RPM that it used to run. What is interesting about this problem is that if I kink the fuel line (essentially shutting it off) while...

    1989 evinrude 175 Crossflow - No power hole shot and low WOT RPM's

    Hello all, I'm having some trouble with my 175. It seems to run great in the tank but when its on the lake it has no power out of the hole and only hits about 3800-4000 rpm at WOT. When running at WOT, it occasionally will surge up to 4200 but then drops off again. The motor ran great last...

    Evinrude Crossflow - Water Diverter Tubes

    175HP 1990 My engine has been overheating. I am installing new water diverter tubes as they were swollen completely closed. My question is, is it normally required to have to trim the new tubes? They stick out from the cyliders about 1/4" which will cause them to be tight up against the head...

    Is this a water port?

    Hi, These pictures are of a 1990ish evinrude V6 Crossflow 175hp. I've been having some overheating problems so I decided to remove the exhaust cover and investigate. All looks pretty good except there is a hole in the upper left corner that was full of calcium. I cleaned it out and it...

    1989 Evinrude 175 Crossflow - Pressure Gauge Problem

    Hello, My water pressure gage doesn't work properly and hasn't since I've owned the boat. Before putting in a new OEM water pump assembly this weekend, the pressure gage would read zero unless I plugged the tell tale with my finger; then it would come up a little bit. I was hoping that after...

    evinrude 175 (1986-ish) - Rough at idle and low speed; runs good at high speed

    Hey Y'All, Saturday the boat wouldn't run. I found there was water in the tanks I guess from when I was pressure washing the boat - lesson learned. I completely drained the tanks then added new fuel. Sunday the boat ran great for most of the morning until it started running rough at idle...

    No ID tag on mounting bracket - any tricks to determine year and hp?

    Hello, I've just bought a boat with an Evinrude outboard. The seller said it's a 175 but he's not sure. I have looked high and low for some sort of an ID tag but have found nothing - not even on the freeze plugs. It originally had a VRO system so according to my manual it has to be 1984 or...
