Here is my story. Purchased a 1985 Bayliner, Volvo Penta I/O AQ125B, Sterndrive 270. First boat, kids wanted a light to med project boat. Well we got it all right.
Here is the final problem, then I will list what I have done and checked.
Problem: While running FOT I only get 2700rpm's and GPS speed = 16, with trim tabs down, can almost get boat to plane. When in reverse, outboard pops up, like it want to come out of water. I get no speed in reverse.
Here is what I have done:
New prop = 15x15L (This matched what was already on boat)
Tune Up, timing is set to 6degr at TDC, while at idle of 800rpm
Compression: 1=184,2=158,3=184,4=184 (Within the specs of 70%)
Temp gauge reads = 180, no signs of it to be wrong
New tachometer
Oil Change
Rebulit Carb
Starts up great, sounds great even at FOT. Manual says cruise RPM = 4500, so I know I am missing some power. When not in gear, RPM's cruise up higher than FOT.
I could really use some advise on what to check next.
I know know what boat stands for: "bout another thousand"
Thanks in advance,
John
