I'm about to purchase a new outboard.<br /><br />I have a Campion 505 (17ft) with a 115 Mercury carburated 2 stroke from 1997.<br /><br />I have decided buying either a Yamaha or Mercury F115. These two outboards should have the same powerhead etc. but the Yamaha is in the specification about 90 lbs heavier than the Merc. <br /><br />Do anybody know why the Yam is heavier than the Merc ? Is it the power trim and gearbox that is more strongly built or ? In that case the Yamaha should be better quality and last longer than the Mercury.<br /><br />I'd appreciate any comments or suggestions.
