I have recently bought a 1989

I have recently bought a 1989 70 horse evinrude for my 16 foot startcraft to repower it.The motor that was on there was a 1985 60 horse evinrude non vro.I installed the engine and a new impeller and water pump and ran the engine all weekend and three times I got a load continuis alarm from my controls.I need some help with this I dont know alot about outboards but have a guy that works with me and he knows quite a bit about them.He says that it may be an oil alarm or an overheat alarm.Should I do the vro disconect and just mix my gas if it is an oil alarm?I like the ease of not mixing my oil and gas so I would like to keep it that way but I dont want to worry about burning it up either.Thanks for the help!
 
"(VRO Horn Warnings)

"(VRO Horn Warnings)
(J. Reeves)

1 - A steady constant beep = Overheating - The V/6 engines, possibly some others, have a fuel restriction warning which is also a steady constant beep.

2 - A beep every 20 or 40 seconds = oil level has dropped to 1/4 tank. (Late model engine = Every 40 seconds)

3 - A beep every other second = VRO failure, air leak in oil line, oil restriction, (anything that would result in a lack of oil being supplied to the engine).

NOTE - If the warning horn is the black plastic (overpriced) three wire type horn, the warning horn should beep once when the ignition key is turned to the ON position. If it does not, it is either faulty or someone has disconnected it (a stupid move!). At any rate, if it does not beep which indicates that the horn is non functional, find out why and do not run the engine until the problem is corrected.

A continuous alarm is an overheat. The VRO low oil is a chirp every 2 minutes or so. No Oil is indicated by a rapid off/on/off/on sequence of the horn.

It is a constant steady beep so I think that it is a overheat alarm.I just had a new impeller and water pump put in it so what do you guys suggest that I try next?

"If the three times that the alarm went off was the last three times that you used the boat, I would suspect that the water pump has picked up some debris and is damaged. In which case, I'd suggest that you drop the lower unit in order to double check that water pump assembly.

If, on the other hand, the three times that the alarm had went off was at some time in the past, and the engine has run okay since then, I'd suspect that the lower unit water intake may have picked up a plastic bag BUT picking up a plastic bag three times in a row would be quite unusal.

Personally, if the compression is okay and there is no sign of a head gasket failure where the combustion could enter the water passages causing a stalemate..... I'd drop the lower unit regardless to make sure of exactly what condition that water pump is in.

Hey Joe I wanted to thank you

Hey Joe I wanted to thank you for your help with my problem we will be tearing into it this week and I will let you know what we find.We are also going to replace the thermostat in the motor to see if that helps.The guy that is doing the work for me says that it is possible that there is an air pocket in the cooling system that may be tripping the alarm.Is there any validity in what he is saying?
 
"There will be no air pocket.

"There will be no air pocket. A slightly leaking head gasket could allow the combustion to enter the water passage area, and that would creste a stalemate..... water hits the combustion power and can go no further. A compression test should show that up."
