Finally got out to try all the spring setup mod's on my Mate.Look's like we went the right direction.Added 5" more setback,boyesen reed's,louver'd the cowl,off with the airbox
"organ pipes".Here is my question.I am running a basicaly stock 1989,200 hp merc,I have the oil injection off,and I am premixing.No internal mod's.My best prop(last year) was a D.A.H. bluprinted yamaha pro.Now with the setup chainges,I am running the engine at almost a 90% angle to the water at my best trim setting,picked up 4 mph,and over 500 rpm!!.
What is it safe to turn a stock 2.4L power head without disaster??I am turning 6500 rpm.Am I on the wrong side of the power curve?? Is there a power curve??Will it will hold up,without excessive wear?I also have a 26p D.A.H. bluprinted chopper(merc big blade)that I havent tried yet this year.
The setback really help'd pick up the bow.I have a total of 11" bolt on,including the c.m.c.jackplate.
I suggest all checkmate owners should inspect the flotation foam in the bow for water soak.I cut it all out in my boat.It was completely full of water.The total weight I removed was over 200# !!! All in the wrong place.
