Greetings, I have twin 1997 4.3ltr mercruiser motors with Alfa1 genII outdrives. the port side has a crack in the outdrive case, so I need to replace it. I'm not sure which gear ratio I have. Any help would be great, Thanks.
I took my boat out on a shakedown cruise. The Starboard engine is a 2009 4.3 carb motor. It always read a constant 40psi, but today was different. After an hour of use, the alarm went on and oil pressure dropped near zero. I shut the motor down for 15 minutes and then restarted it. I got 25psi @...
Boat was dry docked for two years. When stored, the gas was mixed with fuel stabilizer. I have twin 4.3 engines. The port engine doesn't run as it should. It really hesitates between 2000-3500rpm. It stalls if I don't fan the throttle. Idle is good and over 3500rpm is good. So what do you folks...
Boat was dry docked for two years. Trim won't go up on port engine when pushing the trim switch. I could hear the solenoid click, but that's about it. I climbed down into the engine bay and jumped the solenoid and the outdrive went up with no problem. Any idea's b4 I take things apart???
Greetings All,
On my 29' Larson twin 4.3ltr, I switched from twin SS mercury 3 blade 19P x 14-1/4 props to
twin Solas Amita Aluminum 4 blade 17P x 14-1/2" props. NIGHT & DAY IS ALL I CAN SAY!!! Planes so much quicker, I don't even use my trim tabs anymore. Also it's faster out of the hole...
Greetings All,
I have to change the Harmonic Balancer on my 4.3 V6 port engine. I've done it a few times on various cars that I owned and I own a puller and installer. Other then removing the starter and jaming a prybar into the flywheel, is there another way of keeping the crank from...
Greetings all,
Just want to share some good info. I have a horizon/simpson 500 windless on my 1997 29' I/O Larson. I was having trouble with the 12v motor operation last season. Over the winter I took it apart and I could see the motor was a mess from the years salt water operation. A...
Greetings to all who always helps me and saves me money in expensive repairs. My water temp gauge is showing zero. I took off the sending unit wire and put it to ground. The gauge pinned. I took the old sending unit to the marine parts store and told them to match it up for a 4.3 v6 mercruiser...
Does anyone know a reliable person or place that replaces headliners on Long Island. I have a 29' Larson Cabrio and after 10 years the headliner is sagging and discolored. So time to change it. I'm sure it's not cheap.
:( Greetings, I have a 99 Bayliner with a 5.7 mercruiser and Alpha one/ gen II stern drive. When the boat is in gear, I hear a a clattering noise coming from the back of the boat. it doesn't matter if I'm going straight or turning. Before you answer that question, I'll give you the history what...
Greetings,
I have a 1999 Bayliner with a 5.7 mercruiser 250hp that I can't figure out the problem. It started in the begining of this boating season. It was running crappy and stalling. First thing I did was change the water filter and put in water zorb in the tank. This solved the stalling...
Greetings,
I purchased a used 1997 Larson 29' Cabrio boat with new 2008 engines. The drives are Alpha 1/ Gen II
The engines run excellent, but the boat doesn't go faster then 10 mph. It seems past 2500 the props seem to cavitate or spin out. I even tried one engine at a time and...
Greetings, if anyone can help me with my power trim problem there would be a huge weight off my shoulders.
I have a 97 Larson 29' with twin I/O V6. In my driveway the trim worked fine. Since I last trimed it, I put in a new GPS and VHF. When it came to launching the boat, the trim would not go...
