Hey, my question is, I have a 1990 model evinrude 150 hp I have had lots pf trouble with the fuel pump on this outboard , I have found that the file pump is out . The reason I know this is as long as I pump the primer bulb a few times while I'm running down the lake the motor runs like a top as soon as I quit pumping it will die as soon as the fuel in the carbs. Are used. This outboard had the Vro on it but was disconnected I mix my oil and gas. My question is would there be some way of plugging off the pulse hose coming out of the crank case and putting a electric fuel pump on this engine, the actual fuel pump for this engine cost $389.00 without the Vro that's a lot of money to sink up in a motor that is 21 years old. There has to be a way to make a electric pump work. Thanks

Re: Fuel pump trouble

An electric fuel pump on an outboard isn't safe! There are replacement fuel pumps out there if you want to do away with the VRO system and just premix your fuel and are much cheaper than the VRO or a fire! JMO!

Re: Fuel pump trouble

I understand your concern about an electric fuel pump, but Bridgeport outboards have them and the Vro pump on this outboard is electric which connects to the fuel pump.

Re: Fuel pump trouble

Your fuel pump is pulse driven, not electric. If you are in a place that the Coast Guard checks you boat they will bust your chops if you install an electric fuel pump without installing some sort of emercency shut off if the engine quits. It is an easy conversion to mount a pulse type pump, and a lot safer.

Re: Fuel pump trouble

Hey thanks for the reply but I have replaced the bulb all fuel lines rebuilt carbs. All new gaskets and a new fuel filter cleaned out fuel tanks new lines and hoses to them. I sure all it could be is fuel pump.

Hey, I'm nowhere around coast guards, I now the pump is pulse driven. I thought I could hook the electric pump on the key switch which would allow me to kill the power with just a turn of the key.

Re: Fuel pump trouble

This has been discussed to death several times before. The problem is how does the pump get shut off if the engine stalls, the carb floats get stuck, etc. An electric pump in a car or inboard is hooked up through a computer or the oil pressure gauge to shut the pump off, neither of which your motor has. The OMC engineers were not stupid when they used a pulse driven pump on these motors for 50 plus years..

Re: Fuel pump trouble

Agree with tx1961!
Just a bit of info. If, and I mean if a problem happens and you expect your insurance carrier to accept responsibility for the claim. Won't Happen! Infact, I have seen people get cited after an accident for using non marine parts on their boats that cause loss or injury. Plus, they are on the hook for the damages.
Is a few bucks worth this hardship?
JMO!
