    Think I'm Over Propped??

    Hi, I have a 16' Sea Nymph bass boat with a 1972 Johnson 50hp. The motor seems to be in great running condition. It fires right up, has 140+ compression, new carbs etc. etc. I cant get it to run over 15 mph or get it on plane. You guys could estimate the weight of the boat, regular 16 ft'er...

    '55 Johnson lower unit

    Does anyone know what motors the lower unit from a '55 johnson 25hp will fit? I know it will fit the 30hp Johnnys and Evs from '55 and '56. I specifically need to know if it will fit a '56 15hp. Thanks.

    Which Fish Finder?

    Can't decide between Humminbird Piranhamax 170 and the 525c. The 170 has dual cone selector--20 and 60 degrees view and the 525 has speed sensor and higher resolution. I fish mostly in lakes that are 10-60ft deep. Which one would you recommend?

    '77 9.8 hp No Spark

    Hi Guys, I usually do some work on the side repairing 50's and 60's Johnsons and Evinrudes. A guy called me today on this Merc motor asking me to look at it because it has no spark. I'm not familiar with Mercs. I just bought my first one a month ago. Does this motor have coils or a cdi or what...

    1984 90hp Evinrude VRO Disconnect

    Hi guys, I am picking up this motor this weekend and I believe I am more dependable mixing oil and gas for the motor than the motor itself, so I want to disconnect the oil injection system. What's the best way to do it? Oh yeah, what is the mix ratio for this motor? Thanks.

    What Pitch?

    Hi Guys. I just bought a Mercury 40hp motor. The gear ratio is 2.0 It has a 11" diameter and 12" pitch prop. My boat is a 14' semi v that when all told with passengers and gear, motor etc, is probably at 850 lbs. It is rated for a 30hp tiller and 45hp console motor. The boat rockets out of the...

    Will I be ok?

    Hi Guys. I am in the process of rebuilding my 2 short shaft motors for my 14' Aqualine aluminum semi-v, so in the meantime for the rest of the fishing season, I put my 40 hp Merc on it. The transom on the boat is a tad under 16". The shaft on the 40 hp is about 20". Is this going to cause a...

    Some advice on a "new to me" Merc.

    Hi Guys, I've had 3 outboards, but they have all been 50's Johnnys and Rudes. Today I picked up a 1970 Mecury 400 40hp with controls and a tank for $400 for a '63 Starcraft Comet project I'll have going next spring. I started it up, idled great, shifted great, and pumped water nicely. It's got...

    '56 Evinrude 30hp coming out of gear

    I got this motor for free and got her running. I took it out for a test run today and I got about 200 yards and it seemed to come out of gear. The lever was still in the forward position, but the prop wouldn't spin. I tried reverse, it worked a little better than forward, but kind of popped in...

    What do I do now? 1955 25hp Johnson

    So, I have done a carb kit, new plugs, new coils, cleaned and gapped points correctly, compression seems good. Ordered new points and condensers just so it's all new. Still can't get it to stay running. Will fire after about ten hard pulls, runs smoothly for about 5-10 seconds, then dies out...

    Please Help on a '55 Seahorse 25hp

    A motor I just picked up is giving me some problems. It will start, run for a few seconds then die out. I removed the carb, cleaned it spotless, reassembled with new gaskets, and it does the same thing. It's getting fuel in the bowl, and all my lines are good. I also changed the plugs. Seems to...
