    Low Voltage at RPM?

    Fixed!! I put a new alternator in a couple of weeks ago but no improvement. I got to thinking that even though the battery load tested good, it might have an internal short that only showed itself at temperature or after being jostled a bit. The sump pump in my house uses and identical...

    Low Voltage at RPM?

    Thanks again ESG. I've checked the choke (electric as you mentioned), and it opens as it should and stays open. That was one of the first things I thought of. Also, pretty easy to test. I think I'll bite the bullet and buy a new alternator, but one thing to bounce off you before I pull the...

    Low Voltage at RPM?

    Thanks for the quick replies! History: This is my second full summer with this boat. It's a 1991, but it has a 2001 engine. Presumably, someone froze it at some point. It has electronic ignition. It's run like this the whole time I've owned it. It has always run great for the first 10-15...

    Low Voltage at RPM?

    I've got a semi-intermittent problem that I hope the group can help me with. 1991 SeaRay BR17 with a 3.0 Mercruiser. It runs great for the first 10-15 minutes, but once it's good and warmed up it starts to bog and generally run poorly at higher RPMs. When it starts to run bad I've notice that...

    Gear Oil In My Bilge

    A bit of an update. I found the source of the oil leak. It was motor oil leaking around the oil filter gasket. The filter was tight, but I took it off, inspected the gasket (found nothing wrong), cleaned and reinstalled and now it's fine. I also changed the gear lube in the lower unit. I've had...

    MerCruiser 3.0 Runs Poorly As It Warms Up

    I finally solved this one, so I thought I'd put a bow on it in case someone else has the same problem. I replaced the electronic module and pick-up coil in the distributor and now it runs like a champ. I think it was temperature affecting the module, but hard to tell since I swapped two parts at...

    Gear Oil In My Bilge

    No lube reservoir, fresh water and compression is between 160 and 170 on all cylinders. I checked compression with the throttle closed, so that might go up a little if done correctly. I'm leaving town for a week, so it'll be a while before I'm able to spend more time on this. I'll circle back...

    Gear Oil In My Bilge

    Thanks to all for the quick responses. Looks like I've got some things to check out. Scott, my engine oil is clean, clear and still up at the full mark on the dipstick. I had also placed a large piece of paper in the bilge under the engine to see if any drips materialize. It came out clean...

    Gear Oil In My Bilge

    I replaced the manifold gasket because I thought it was leaking (sucking air). That may or may not have been the case. Still chasing that one down. My engine oil is clean. No water is getting in there. It's the gear lube that has issues. The head gasket or the manifold gasket could be the...

    Gear Oil In My Bilge

    My boat has a new problem, or combination of problems I'm hoping to get some thoughts on. 2003 Mercruiser 3.0 with Alpha 1 Gen 2. The boat's new to me (bought it last fall), and the first several times I had it out, the bilge stayed almost completely dry. But when returning from the last couple...

    MerCruiser 3.0 Runs Poorly As It Warms Up

    I'm pretty sure I removed the PV and cleaned the passages, but one more time can't hurt. Just for grins, I've ordered a new float (they're relatively cheap). When that gets here I'll check the power valve while I'm installing it. My ignition is the typical electronic type with single coil and...

    MerCruiser 3.0 Runs Poorly As It Warms Up

    Thanks Scott. The jets were removed and cleaned, and the carb was really pretty clean inside. Unfortunately, I don't have an ultrasonic cleaner, but it may be worth the investment. I've had plenty of opportunities to use one over the years. The power valve might be worth taking another look...
