    Mercruiser unsteady under load.

    I have a 1990 5.7 mercruiser ski inboard. It runs OK with no load up to 3000 RPMs. But when I put the throttle down it usually won't take it. It will occasionally run up to about 4200 RPMs when colder but is inconsistant. Trying to pull out a skier just results in sputtering. I've been through...

    Too much water pressure!

    After installing a Nosecone so that I could raise my engine for more rpm's, I now find that with the low water pickup my water pressure is excessive 30-40 psi and higher at high speeds. Can this hurt the engine by blowing out any seals or is it completely regulated by the impeller. (1997 Johnson...

    Finding a good tech???

    Does anyone know how I could find a good technician/mechanic in the Bay area in California. I have a Johnson 225 which just doesn't quite reach it's WOT RPM's and I've done everything I know how to do. I need a diagnosis.<br />How involved/expensive is it to have a motor dyno tested?

    Transom mounted water pickup

    Has anybody used a transom mounted water pickup. I need to get my motor up higher to get the rpm's but am at the point now 1 1/2" below pad that if I go any higher, I will lose water pressure. Will one of these devises give me enough water? Thanks

    Fresh powerhead, new powerpack, good comp.,light boat, worked 26P prop, engine at 2" below pad -- can only get 5200 RPM's. Am pulling my hair out trying to figure what's wrong. Can timing be the problem? Coils?<br /><br />Thanks

    Question for Joe / 225 Johnson Venom

    I've got a 97 225 Venom on a 96 Bullet (1200 lbs.) 4B 27" renegade prop at 2" below pad with 12" setback. Engine has fresh powerhead and runs great but won't get more than 5200-5400 RPM's. This rig in the past would easily turn 5900-6000 RPM's. Any suggestions of things to check?? Thanks in...

    Johnson Venom trim sensor

    I've posted before on this subject but still can't figure it out. Trim gauge not working. Gauge tests out OK when I ground the S terminal. Bought a new sender. It checks out OK on the ohm meter. The gauge still doesn't work. I tested continuity on the white/brown wire from the sender to the S...

    Johnson 225 Venom trim gauge

    My trim gauge on my 225 Venom was not working. I<br />replaced the gauge - still not working. I could use some trouble shooting help. Do I just replace the sending unit or is there a way to troubleshoot it first?? If it turns out to be the sending unit where is the best place to get one??<br...

    T-stats.

    My 1997 Johnson 225 Venom has not been run for about a year and a half (I just bought it). I'm told that I should replace the water pump, clean the carbs, put in new fuel (with a little oil in it as the engine still only has about 30 hrs. on a rebuild), and service/replace the t-stas. What are...
