Re: Boysen reed valves or NOT ???
This is 2nd hand info, but perhaps it will help. Fiber reeds are used in high rpm applications. Usually 6500+. For speed junkies they are needed because steel reeds will break when pushed that hard, that spells disaster for your Merc. The Fiber reeds will fatigue much quicker than steel ans as a result need to be replaced with some frequency, steel should last you 1,000s of hrs. By themselves Fiber reeds aren't going to make your boat perform all that different, esp at 90 hp ( it is the rpm increase that does it). You should be in the 5500 range with that Merc @ wot. Another 1000 rpm and the rest of that engine will get un- happy. That old 86 inline is one of the best they made, I believe it is the same as the old 1150 before the HP ratings changed. I have burnt an old Merc and did it because I pushed it too hard. That 300-400 extra rpm was fun till a hole blew through the block...<br />If you are going to push it use the best gas and synthetic oil, and run it at 40 to 1 instead of 50. That will keep it slippery. <br /><br />There are lots of different opinions out there, but with that old Merc I would run it as close to spec as you can
but have great compression, good fire and plenty of good fuel... That's Y I'm into the carb thing right now, never done any carb work that's Y I toke to shop... Plus I wanted her done yesterday because I'm ready to get back in the water to chase the Rock Fish, They start to run end of this month begin'n of next...<br /><br />Charge'n thing should be you stator??? correct or are you have'n other problems???<br />I think I have the correct OHM readings in my book for testing the stator on your beast if you haven't done so. If you would like I could send some readings for trigger, stator, rectifier, ect...
