I have a 60 HP 4 stroke EFI Mercury on my 20 foot pontoon and my bud on the next dock sold his 2 stroke because he loved my motor so much better. quiet, starts every time and sips gas. Simple to maintain and as we don't have it full out much except couple times a year when grandkids want to be pulled on the tube, we are mostly in cruise around mode till it's time to get home straight on.
