1990 Four Winns Vista 245 1990 OMC 5.7 350 chevy with cobra out drive
Bought the boat last week, took it out yesterday for the first test run. Here is what I have done prior to the test run, and a brief history of the boat,
Changed engine oil, greased splines and gimbals, checked all fluid levels and topped off where necessary, added 20 gallons of fresh premium gas,
Single owner boat since 1990, stored winters and taken care of, engine runs great, but has not been run for 2 years.
Here's the problem, While sitting at idle in both neutral, and drive, the low oil alarm blares (oil is topped off perfectly in the "safe"zone on the dipstick) . As soon as it is given throttle the alarm stops.
The alarm didn't sound until I put brand new oil in, I ran it with the old stuff for about 10 minutes in order to change it.
After pulling out of the water yesterday (first test run!), I did notice that the lower stern drive rubber transom seal exhaust bellows was shot. Old, Crusty, falling to pieces. Have a replacement on the way.
Question.....Could the lack of back pressure from the exhaust not being directed through the lower unit housing cause the low oil alarm to sound?
I'm really hoping this isn't going to be an oil pump issue, do not want to have to pull the whole motor to replace that thing.
Also, Carb (Holley) is a little dirty, will be pulling and cleaning this week as soon as the replacement gasket comes in.
Engine runs great from just above idle, all the way through wide open, and also into long arcing turns at top speed. Alarm only sounds at idle.
Any thoughts or suggestions are much appreciated! LouC? ric? Anyone?
Have a few nights trip planned for may over on lake powell, and want to make sure all is well.
Thanks in advance for any replies!
