if you have marine pistons.. you have to make sure they have the correct spray patern or they will cause to much heat and smoke

they are a dirty injector but you can make good power with them many people have and will continue to just make sure you have plenty of airflow

you can also use different copper washers between the head and injector to make them spray into the bowl rather than around it, thats why i had so low egts when i had the 370's

they will give you power...! but if you want to reach 500+ HP efficiently then you need to go with a better injector.. like the DDP 90 horsepower. they are expensive but worth the money. i am currently running the 370 marines.. but i am going to upgrade asap

You can fin injectors with the proper spray for just a little more and mpg will more than pay for itself.

bumping your timing will also help with marine injectors 16.5* - 17* works well with 370's

I agree spend the extra $150 and get a good clean injector thats gonna make more power, run better, and save you fuel.
