I meant that I'd probably make the pump repair whether that's for one or both engines. Two 250's can burn a lot of fuel and I'd hate to mix that much.

I agree, plus the other motor is working fine. If you can afford a ocean going boat with twin 250s, you can afford the couple hundred dollars to replace the pump.

Heck, if you can afford the fuel for a boat like that the cost of the pump repair shouldn't hurt you too bad. Usually replacing a pump like that isn't that much of a job. The designer of the system surely would have designed it so that it lent itself to be readily serviced. But, then I think that way because I was a mechanic not an engineer. You have to make sure you get it primed correctly. On motorcycles I'd prime them using an electric drill.

Yep,I've done the same thing on rblt V8s, spin the pump with a drill.

When I was younger I was an automotive machinist and I've rebuilt almost every kind of engine from a 3.5 hp Briggs to D8 Cat engines. Even did a valve job on a set of heads off a Cooper-Bessemer engine. I still have one of the old valves we replaced. Big sucker! I finally got out of the automotive field and became a millwright installing and maintaining high speed production machinery. The pay was much better.
I used to be involved in motorcycle racing with two stroke powered machines. We raced Suzuki's but built engines for most other makes for other people including the two-stroke Harley Davidson / Aermacchi motorcycles of the 60's and 70's. Even the Harley dealerships didn't like those bikes because they were two stroke and metric sized. I preferred metric over the early Brit stuff that was Whitworth and British standard sized tooling.

To be honest the oil pump could easily be a fuel and oil pump so may need it to pump fuel on one side of pulse diaphragm. They are very in expensive and very easy to change. You can add oil to fuel but you will be measuring the oil from now on. You will probably have to modify both motors too. I would fix what you have but its your machine.
I agree put a new oil pump on it and be done with it. I mix seafoam with my oil at least once a year

My 115 evenrude started using twice the oil that it should. Oil would drain out of the lower unit, and inside motor cover. Everyone i talked to about it said take the oil injection out. A friend has a marine repair shop, he said the same thing. He disconected it for me(no charge), motor runs a lot better. I buy bulk oil, pour it into qt containers store in place of oil tank. I can put 2 1/2 gallons there in qts, for 12 gal of gas. That will last me 2 weeks to a month. I have not had a problem sinse, 4 years ago. 2004 , 115 evenrude. DEEJAY

We all ran premix for many decades before oil injection came along.
Unless you messed up and forgot to mix in the oil, oil-related problems were very rare.
About the commonest problem was fouled plugs caused by cautious users who mixed in too much.
