Re: 1998 evinrude intruder 115 ficht

On the carbed engines, it's normal for engines to slightly increase rpm's as they run out of fuel. They like to run lean, but a constant dose of lean mixture will kill the engine- so the factory has to fatten up the jets for normal operation. Not sure if the direct inject engines work the same way.

Pretty sure I found my problem, I found a crack on the #2 cylinder head. Now my question is with the crack do I need to rebuild the pistons or can I just replace the cylinder head? And how much am I looking at spending for my problem? Thank yous in advance on your input

I checked the price. $125.00 for a replacement head. It's a drop ship from a dealership, Witch means it may take some time to receive it.

Are you working on this direct inject engine without a factory service manual?

If you're are working on this mtr with out a factory service manual, as the old saying goes "you're peeing in the wind ".
