It is a 42 foot provincial commercial tuna boat annual hour 400 to 500 with a new last
Last November recon qsm 11 670.fiberglass fuel tanks 15 years old no algae problems
Ever.racor 1000 present 5/8 fuel supply and return. Never have water in the racor really
Really just looking for more insurance and cleaner fuel . I had your double double
On my qsc500 loved it so easy to monitor with the vacuum gauges.
Just another thought engine propped the way you say 2300 90 percent

Here is what I found

No when I installed my system everything worked fine just couldn’t get it to full throttle. Yes they replace the processor and all was good . In my boat now I have a zf system that you have to go into the menu and set the voltage for the engine have if it remember correctly it was 3 to 4.7 volts for my qsm11

I have done this no matter what direction I will get 2370 fuel burn is 30.1  to 29.6 speed is 24 knots in 42 provincial  so tony I can safely run say 2100 if I am in a hurry . I took a long time choosing my gear to get where you say and want a long trouble free exhaust and turbo . I do go 50 to 75 fish quite often so getting my best safe cruise is what I am looking for

Ok thank you so what you are saying is I am good on what tony recommends for good manifold life that’s what I want so I guess I am going to save my money and stick with my current prop

I had the same problem before with my Glendenning system on a qsc 500 I ended up having the wrong voltage coming from my controller to the engine sent it back they fixed it and overnighted it back

I I am just looking to know as I am going to get a new prop and would like to start off close to where I am

Thank you
