Check your WOT rpms. Look to see what your engines need to be at @ WOT 5600 rpms? and make sure that boat is propped correctly. It will run peak performance and economically as well when its propped right, go stainless or X7 alloy type props. B.O.A.T. "break out another thousand" Enertia are beautiful props! But there are many others besides.Go out with a typical load ( fuel and weight when this is being done )and record your rpms, gpm (if you can), and speed @ 3000 ,3500,3800, 4000, 4300, 4500, 5000, 5500. and so forth all the way up to you WOT recommended rpms. If you can go over your spec, your under propped and if you are below that recommended rpm your over propped. You can Talk to Ken2 @ prop gods he knows his stuff, I just got done dealing with him and got my trohy propped right, and what a difference. The rule of thumb is 1 inch of pitch higher will loose 200 rpms and 1 inch in pith lower will gain 200 rpms take those performance no3 and post them for ken and he'll know what to suggest OH! you'll need to know what diameter and pitch your props are to start, they will be stamped on the prop it self either on the outide or inside where the prop nut is, talking to a pro. will save you dollars, so be where of friend s that know it all! ( I went through that myself )Being at the right rpm at WOT will make your engines happy at all rpms and last you longer and perform better, with fuel economy. I went from stock alumin. to stainless and should have done that along time ago. my boat handling and fuel economy has increased. I get on ave 1/4 mpg more per ml, with my 100 gal gas tank thats 25 more mls per tank! I'll take that! so instead of long range being approx. 200 mls , I around 225 per tankful, and you do understand that depends on the wind, the seas, and my hand on the throttle. Have fun, Boating and fishing is ADDICTIVE!
