From what I've read in the service manuals, the pump gets 12V when the engine is cranking, and then via a fuel cut off oil pressure switch when the engine is running. I have two questions. First, is the pump supposed to run continuously while the engine is running assuming there is oil...
Can anyone comment on why my motor would only start bogging down after an hour or two of skiing and tubing? It always starts easy, runs smooth, has great take off, but after about 1 to 2 hours of usage on the lake, I'll notice it suddenly takes longer to get on plane, and then it will surge...
First season out on a 1995 4.3LX alpha one. Been running great. Last couple times on the water, after an hour or two of skiing and tubing, I will notice that the time to get on plane takes a little longer, and then soon after getting on plane takes longer, it will start bogging at WOT or...
I need info about actual temperatures I should see with my IR thermometer with my 4.3LX 1995 motor. - I tried reading lots of posts about overheating but didn't come across actual temperatures being mentioned around certain parts of the motor.
After running 15 minutes on muffs- I measure...
I have a 1995 4.3LX alpha one with a seawater cooling system (not closed system).
Couple questions.
If I want to remove the Tstat and do a test in a pot of water- do I really have to completely drain all the water out of the engine like my Clymer manual is telling me- it's also telling me...
I had steering play in my stern drive. After tightening the gimble ring clamping bolts to 55 ft pounds, almost all of the play is gone. Before I could see the gimble ring moving on the square insert. Now that both are tightened, the square insert and ring move as one and are nice and...
I may not be using the right terminology here, but if I grab my stern drive I can move it left to right about an inch without the steering wheel moving. Should there be this much left and right play in the gimble/swivel mount of the stern drive or should the steering linkage be stiff and not...
Took off my lower unit to replace the impeller and do water pump service, and when I separated the lower unit, there was quite a bit of gear oil on the drive shaft in/around the spine where the drive shaft inserts into. Easily a couple tablespoons maybe more. It dripped out when I separated...
If I'm not sure my dashboard temp guage is accurate and I have an IR thermometer... where are the best places to aim my IR thermometer on the engine to get a good reading of the engine's temperature?
Dumb question I suppose. This is my first alpha one genII - on a 1996 4.3LX. My previous boat had an old 2 stroke outboard and I was used to all the water and exhaust going through the prop. Can someone explain the normal path for water and exhaust on an Alpha One Gen 2 stern drive-...
This is more of a question of whether muff testing will verify if you have a water intrusion problem than necessarily telling you what kind of water intrusion you have.
But after I've inspected risers, manifolds etc etc- and I want to be confident I don't still have water coming in anywhere...
Just bought this boat. I can't find an hour meter anywhere on the dash. No missing guages are evident. All analog. RPM, MPH, Temp, Oil Pressure, Trim, Fuel are all around the steering wheel, but no hour meter. Is there a place on the engine itself where an hour meter is- or was it not...
I bought a boat with not much known about it's history.
Previous owner winterized the boat (verified in the fall by me) and he abandoned the boat with a sheered starter motor boat. No other history is known. I left it in dry dock until now.
I didn't try to repair the starter and turn over...
I like to keep a spare lower unit handy for my 1972 Johnson V4 100 100ESL72R motor. That way if it leaks or fails, I can swap lowers and worry about fixing the bad one later.
I bought a good looking spare unit on ebay. Problem is it doesn't have a thrust bushing. This gear case is slightly...
Looking for a recommendation on some really good gasket sealer that will adhere between rubber and metal.
I Noticed water was getting into my lower unit gear oil and I'd see the tinest trails of gear oil leaking when I was parked at the marina. I dropped the lower unit, and pressured up...
