    Positioning of shaft seals

    I have just replaced both shaft seals on my E150EXERV. When I pressed the first seal into the carrier I pushed it in possibly too far, but not yet touching the bearing. The outer seal was flush with the carrier and when I pressed the second seal in there is about 1/8 inch gap between the two...

    Lower unit oil -- water or not?

    I normally use Mercury or Yamaha lower unit oil which is dyed blue. When I drain it after a season of use it is normally pretty dark and no signs of water. Recently I hit something hard, destroyed a stainless prop. The shaft still looks straight, but I decided to drain the oil anyway. There...

    Removing trim rod Evinrude E150EXERV

    I've replaced my trim motor and to get to it on my motor the trim rod must be removed at a minimum. I've read about this and it seems most of them get stuck after years of use. The consensus seems to be heat/beat with brass punch, penetrating oil, repeat, for days if necessary. I thought I'd...

    Trim rod size

    I'm preparing to replace the trim/tilt motor on my 150 E150EXERV '96. The manual says I need to remove the trim rods etc. I have the old retaining clips out and managed to drop one and lose it somewhere, and I think it's a good idea to just replace all of them anyway as long as I have it...

    Tilt motor bad?

    I have my boat and motor pretty much overhauled and today I went to run the motor on the muffs and in the process discovered the trim motor wasn't responding. The motor was tilted up at the time. I found the wires to the trim motor to have been crushed somehow between the motor mounts. I...

    Fuel restriction alarm

    I'm getting a "no oil" alarm (beep every other second) from my VRO. I've tested according to the book by using a clear hose with 1/2" marks. When I run the motor at idle I see the oil level in the clear tube drop according to specs (3 inches in 6-8 pulses). I cannot hear or feel the "clicks"...

    Blown head gasket / overheat

    I'm getting overheat horns in the following way: Let idle for 10 minutes -- temp readings within spec Run 4K RPM for 15 minutes -- overheat warning horn. Stop the boat, turn off the motor for about 1-2 minutes, restart and go on my way. 4K RPM for 5 more minutes, same overheat. Start...

    Cleaning water passages Evinrude E150EXERV

    Once I removed the head I found most of the smaller passages plugged with salt. Problem is, the block has more passages than the head does. Where the two meet you can see a salt/corrosion mark on the head. Why is this? Perhaps this head fits a few different blocks or vice versa? Anyhow the...

    Air leak in fuel pump? Evinrude '94 E150EXERV

    Currently motor runs fine at idle and runs fine on a plane for about 20 seconds then she just loses power as if there is not enough fuel. Removed the water pump (newly rebuilt) and found a broken diaphram, so I put the old one (not torn) back in. Still same problem, so I installed a clear hose...

    Evinrude '94 150hp E150EXERV overheating

    Hello, hopefully I can get a few questions answered re: the cooling system on my Evinrude. I've been getting overheat alarms. I replaced the thermostats (both bad) and the port and starboard overheat sensors (both bad). My SELOC manual says to take temperature readings with a heat crayon or...
