'89 Evinrude 100hp V-4..'89 17 SSL. Midseason I disconnected the VRO and now run on pre-mixed fuel, I replaced the power pack, starter motor and gave it a general tune up. Relatively new to boating I thought, new and bigger was better and coveted the newer 4 stroke motors, then I got a reply from one of ContinuousWaves patron who said, "that engine is a great one and if cared for, will run forever." Tests show one cylinder has lower compression, 80 compare to 110 on the others and I need to replace the water pump and possibly the VRO pump as well. Winter is coming quickly to New England and I am thinking of having my rude "fixed" during the off season. And my question is, what can I expect to pay for this work, is it worth it? And finally can anyone in the Boston area recommend a marine mechanic.

The VRO pump is no longer being used on your motor to pump oil because you are premixing. The are no effective after markets so you are looking at +$250 for another VRO UNLESS you simply replace with standard OMC fuel pump for about $50. Find a marine mechanic that knows what UIm talking about becuase this can be done and is not expensive.

The water pump on that type motor will last forever. Its the old metal ones not todays plastics that need to be replaced every 3 years. If its "pissin" than your okay.

Thanks Capt. I have read and re-read the many discussions on the VRO and concluded that I can run successfully without it, however, I do anticipate fuel pump problems and want replace it this winter, glad to know I can just replace the fuel pump and not spend $250 on the VRO.
The water pump is working, 'pissin' like a champ. Heard changing the themostats on this motor is a headache. any experienc with them.

Easy to do as long as all your head bolts come loose and don't snap. I personally would not worry about them.

As far as waterpump goes....yes the housing has a stainless liner but that does wear and impellers go bad. Replace at least every 3 years.
