:huh:Hello all I have a 87 21' Searay Seville. I have the 4.3 with 175hp. It has trim tabs and a hydrofoil. At wot I only hit 3600 rpms and 31mph on gps. I know I am supposed to get 4400-4600 rpm. It has a 14x19p prop in good condition. It runs like a top idles great and gets up to speed well. But its not hitting the right rpm range. Please help I am praying it is not a motor issue.
PS I am going to replace plugs next time.
Thanks in advance
