I certainly don't worry about trolling with my main. I've fished on boats with kickers, but find the constant noise created by kickers annoying. I can barely hear my main while trolling. Burns about 0.3GPH, too, so no big deal.Buddy of mine just bought a boat with twin HPDI’s. Being 2-strokes gave him pause, but his research indicated they are superb motors.
My 9.9 Yammie kicker was dead as a doornail once I got onto the water Friday, (turned out to be a rotted battery cable) so I put 5 hours on the main trolling for salmon. Normally I prefer to NOT put hours on the main like that.... reading this thread makes me wonder why I worry!
Tight lines and smooth runnin’ guys.
