Last summer my 1993 Force 150 outboard suffered damage to #3 and #4 pistons when, apparently, one ring failed triggering an overheat and subsequent damage to the adjoining piston. This is an engine that had already had the #1 piston replaced for a similar reason. With that experience, I have decided to replace all the remaining original pistons. ... Having done #1 already, I know how to do the job, but I have questions about the best way to approach replacing the #5 piston.
The cowl obstructs an easy view into the #5 cylinder. That leaves me to choose from three apparent options. One, leave everything in place and do the job while working around the impediments created by the cowl. Two, remove the cowl. And three, remove the powerhead to do the job. Options 2 & 3 involve a lot more work, so I'd like to hear from any who have experience doing this job. If you'd like to share your opinion on the best way to do this job, please note whether you have actually done it.
