I have a set of 260hp yanmar 6LP injectors. My intention is to fit these to my 245hp Yamaha ME422 giving me a 15hp increase in power and hopefully earlier turbo spooling. My current prop is perfect for the boat and all I need is a tad more power and I'll be happy. Has anybody tried this? Obviously I will have to adjust the pump slightly but I don't see this as an issue. Thoughts?
It won't work they run at different compression ratios therefor different injector pressures.
You may get a little extra by messing with the boost controller and fueling but the yanmar runs a much bigger turbo than the yamaha so you might not be able to play with the boost enough
