I just bought this boat. I cant get it to idle very smooth at the 700 rpm the operation manual says. At 900 rpm she will idle smooth. The ser # is 0g077943 is this a 20 hp or a 25 hp and what would be a good after market manual to pick up. i di find that the LINK-SPARK ADJUSTMENT rod ball that is screwed in to the block is broken. I take it that the crank trigger is adjustable??
I am a master diesel tech. can any body give any pointers thanks
