Sterndrive ratio causing low speed/low rpm?
Good Afternoon!
I bought a 1996 Maxum 2100 SR a couple months ago for my first boat.
I took my wife, 8yo son and 3yo daughter for the first ride/shakedown with a bunch of friends from our campground to make sure all is well. Well, it floats and runs, so that's all good lol
Only issue I'm having is it seems to be a little down on power/speed. Based on other maxum owners, they're seeing 50+ at 4600 rpms with a 15x19. Right now, my top speed is 40 at 4200 rpms. We used a few phone gps apps to gauge accuracy across apps.
I look a little deeper into the prop, it's a quicksilver 16x19, but the sterndrive is showing 1.79 or 1.78 gearing. I've seen quite a few people say that gearing is more for a v6, so I'm wondering if that could be why I'm not seeing the same speed as others.
