I know of one dealer friend that gave up Evinrude dealer status 20 years ago with the early FICHT models.-----Refused to sell unproven technology to his customers.-----As it wasted too much time ( not paid for ) in talking to / helping people out.
Looked at a 1990 model 90 HP yesterday.-----Looked at the sparkplugs.---- Then popped off the cylinder head..----Found cylinders scored on #1 and 3.---Likely 2 and 4 as well.----Bone dry cylinders with no sign of oil.-----Winter work with 0.020" over WISECO pistons.----Nothing to it.
There you go it was a V-6 !!-----Chris 56 I think the Evinrude name in new outboards is done.-----They might do better with another name if they decide to build outboard motors again !!
What year did Evinrude market an " inline 4 " model 175 HP E-TEC ????-----There seems to be a trend towards V-8 motors for big outboard 4 strokes.-----Yamaha 425 HP for one.---

The cavity for the long bolts gets water / moisture in there.-----Possibly salt water.-----Then NATURE takes over and OXYGEN joins with the aluminum,-----The white powder is aluminum oxide.-----There is now more material there since oxygen has packed itself in there one molecule at a...
Perform a check on magneto belt timing.----Belt timing might be off.----Or plug wires going to the wrong cylinders.----Does spark jump a gap of 5/16" on all of the 4 leads ?
