Ok first, yes, I should have winterized, but we really expected to get good boating weather during the last three months based on last year. Went to marina to check on the boat. All good. Put water muffs on 2015 Mercruiser 350 Mag MPI and it just cranks. Has always started easily. Stopped after trying the Mercury hard starting instructions, realizing it would do no good until I addressed whatever the issue is. Need to change fuel filter and will do that next, but any thoughts of what else to do/check before trying again. Prefer it crank right up. Unlikely it is not getting spark. I will confirm fuel flow. In the winter (it is not that cold in coastal GA) I have a hard time believing fuel would gum up that quick, and that would be counter to my last 40 years of engine experience.
