eBay and Amazon injectors a commonly poor copied of the real thing. I’d stay away from them.

The older ones were 805225A1, shows crossing to Mallory 9-33100 but not many have tried them that I'm aware of

The later style used 861260T which cross to Mallory 9-33101

those look like mercury part numbers. Not sure if marine power used the same? Pfi probably stands for port fuel injection

Yes, pfi port fuel injection!!!👍👍👍

​​​​​​It is probably same gm 8.2 engine with any difference in throttle module and injection systems

Came up as 3rd result when I seached ‘Marine Power 502.’

Also, if your in the states you can send to a good injector place like member ArcticFriends. They can go thru them and if replacement needed, will probably have a good teplacement.

Thank you. Unfortunately, not from US(

it is great idea about injectors remanufacturing.

Already downloaded.

but it is mpi, not pfi.

Do you think it is the same?

Another problem - 0730500 no longer available 😳"​
