Need outboard expert

[cavu]

Who is the outboard motor expert here? I need info on outboard motors (2 150 HP Johnsons, 1997) which have a remote oil tank. The only experience I have is with my 90 HP Yamaha which has the tank build into the motor. Are the remote oil tanks dependable or is this where the oil injected motors got an initial bad rap?

I've been running Evinrude/Johnson for 20 years now. In that time, I've had one VRO pump go bad. That was the first year they came out with the thing. Needless to say that 150 flew into many pieces. I've not had one to fail since and that was in the neighborhood of 5 motors ago. They've all had the external oil tank. Have never had any problems with it. Merc & Yammy both have external tanks. I know some Yammies had the internal tank but most of the newer ones have the external. They are no problem.

Todays 2 stroke outboards(and yes the 97 150's)are equiped with remote 2 cycle oil tanks.The purpose # 1 is evolution.Most boats that will rate for an engine that large will also have more fuel capacity.More fuel capacity = more oil consumption.It is not practical to mount a 4 gallon oil tank on an engine.

Second,it is much easier to fill the oil tank without pulling the engine cowl because thats were it would have to be located if mounted to the engine.

Larger 2 stroke engines (new and old) are equiped with an auxilary tank mounted to the engine that holds about 1 quart of oil.The purpose for this is so if for some reason the oil stops flowing from the tank,it can be fed from the auxilary and prevent damage to the engine.

VRO pump failure is rare.As with anything mechanical,regular engine maintenance and checks are important and can prevent alot of problems.
