You can buy an engine skeg mounted tab and fix the problem without playing around. I run these on all my tiller motors- usually cut to around 1 or 1.5 inch height, and use them full length on my...

I run a 2004 Merc 15hp 2 stroke on my inland boat- a little 14 ft. rig. I've run it on E10 ever since new with no problems. I experimented 2 years back with both 89 octane E10 and Rec gas. The...

Your present 1.75 cav plate above the bottom is roughly in the ballpark for a rig with a decent ss prop running in the 55 mph range. It never hurts to try the motor up another hole unless you notice...

I’ve had great results from Mark as have other posters. Prop guys are getting a bit hard to find. I used to use Rich Boger down south but he had to retire with health issues. I also have used Hill...

OMG- looks like the idiot who changed the plugs was a total incompetent! I taught my daughter at age 6 how to change plugs in a 1938 Muncie Neptune 5hp I had kicking around- and she did a better job...

It depends on what you're trolling for. I run a Starcraft SF-176 side console with a 150 Merc 4 stroke- it trolls stick baits for walleye and bass nicely and I have to speed up some more for musky....

My Opti 150 would vibrate some when going on plane if the plugs needed to be changed- and carefully gapped- or if I had't got one of the lowest plug wires completely snapped down onto place.

Some years back I had a 16ft Starcraft tiller with a 25 Merc on it. Fishing was OK but planing off was difficult unless I had someone up front. In addition, my kids wanted to tube and ski and thought...

I switched to the non-ethanol gas in my 150 4S and 15 2S Mercs a year or so back. I was not happy with the results- both motors were harder to start and the 15 hp started to miss at trolling speeds....
