    fuel guage + other problems

    the fuel guage on my '99 SeaRay 210 BR quit working, so I had the local shop pull the sending unit with the idea of replacing it--they checked it out once it was out of the tank and said that it worked fine-sent the right message to the gauge, etc.---now it's not working again and neither are...

    alternator either charging too much, or not enough

    1999 mercruiser 5.7 EFI--battery meter on console shows 12 volts on start up & warm up phase-but goes to 14 + volts upon increasing RPMs over 1200-and stays there all day (until engine shut down-and restarting = 12 volts again). The battery is fairly new, and fully charged with an automatic...

    am-fm radio not working

    even though this is a Clarion Marine am-fm-cd radio, I think all the moisture that managed to get into my boat last winter has done something to it. All I can get is a faint flickering in the LCD screen--no codes, numbers, noise. I'd appreciate advice on where to start trouble shooting (I've...

    ROCKY MOUNTAIN ENGINES

    Has any one dealt with these folks? I was told that they have been rebuilding marine motors for 30+ years. Claim to have less than 3% return rate on their rebuilds (that's good, isn't it?).<br /><br />I've got one on order, just wanted to check them out more.<br /><br />Also, can you tell a GM...

    will Mercruiser replace an engine?

    Just found out that my third set of heads have cracked. '99 5.7 EFI with about 165 hrs. on it (bought new in '01-so this is the fourth boating season). I've had the OBC checked, and no recorded spikes, nor did the alarm go off. The impeller has been repaced each spring, and new t-stat...

    Water Temp--what's too hot?

    My '99 5.7 EFI w/Alpha 1 runs fine at 3200 rpm or less, but a long run at 4,000 + rpm brings the sometimes working temp gauge up to the 220 mark. No alarms go off, as I watch the guage and bring the rpms back down to 3,000-and the temp gauge drops back to 160-170 area. I'm running a new 160...

    water temperature gauge problem

    I have a '99 5.7 EFI Mercruiser with a 160 degree thermostat. The guage will not register most of the time. I have tested the gauge to ground, and it pegs all the way over. If I shut the motor down after warm up, wait a few minutes, and turn the ignition on, the gauge will register 160 until I...

    cost of cylinder head R & R

    I need advice from a boat mechanic. My cylinder heads have cracked (second time in a year) and the shop doing the work is quoting 20 hours "according to the Mercury Manual" to do the work-at $75 hourly rate. The new Vortec heads for my '99 5.7 EFI Mercrusier are costing $300+ each. The last...

    Temp Guage Fluctuation

    My '99 SeaRay temp guage for the 350 EFI / Alpha 1 system is driving me nuts! It will fluctuate from 170 to <130 degrees and back as I run across the lake. The temp stays higher at 4200+ RPM than at 3400 RPM. The impeller was replaced by an authorized dealer a few months ago. I replaced the...

    I have an almost new 15.5 x 17 SS Mercury Mirage Plus Bravo One prop that the original dealer mistakingly (?) installed on my boat. I have replaced it with the proper 14.5 x 17 prop for my Alpha 1 drive(at my own expense since the dealer went out of business shortly after I bought my boat)--I...
