I have a 15 HP, a lot of motor but the good thing is at motor idle it nearly hits hull speed, so it's quiet and plenty left if needed
When I was in the market for a new OB I compared quite a few and settled on a Yamaha 9.9 w/ electric start. Then the marina owner suggested power trim so the Admiral could easily lower and start the OB. We're glad we went with the option as now she frequently will take over the starting and stopping of the OB while I do other things.I fractured and screwed up my shoulder and couldn't pull start the outboard for 3 days and neither could Ruth so we sat in a remote side canyon. That was how we came to the conclusion that we needed electric start for safety purposes.
