Let me first start by thanking everyone in these forums!! I have learned so much over the past few weeks just scrolling all the other posts.
So here is my problem, I just bought a 1986 Aries 150 (15 foot) bass boat, it came with matching 1986 mercury 90 hp inline six, the boat had been sitting for 4 - 5 years and was in need of a lot of cleaning. so after emptying all the junk and debris, we rebuilt the carbs, replaced the stator and trigger to correct the lack of spark problem. Now she is running great in the yard on the hose but wont run well enough to get on plane at the lake. I have done the link and sync procedure I found on here in the engine forum, and its all timed and has great compression all cylinders are around 122 -125 I believe it is way over propped?? when clening out the boat i removed two 50 pound bags of concrete and a large chunk of steel from the bow storage area! I'm guessing this was used to counterbalance the boat and assist in leveling it out when trying to get on plane? I have removed the 3 blade stainless prop and can find no markings on the hub or blades. I have no idea what my rpm's would be at WOT because I cant get her to wind up on the lake! so where do I start? should I put all the extra weight back in the boat and see what I get or could someone give me a starting point? what size prop would i need for a 750 pound 15 foot bass boat with a 90 hp inline 6?
