I have a 1999 Four Winns 245 Sundowner with a 5.7 GSI "pwtr" engine. This is my 2nd season with it and my problem is giving it power to get up on plane. It will start fine when cold,Idle all day,,go down the river nice,Never stalls. But when I get out of the river and go to throttle up it's hardly moving,,But it never stalls,bogs etc.
It seems that my rpms wont go over around 2200. It will take a bit,like maybe a 1/4 to 1/2 mile but it will gradually pick up speed and eventually get on plane,,then goes fine. RPM's will raise and can cruise just fine at around 28-30mph and around 3000-3200rpm.
I went over and checked a few things,Like replaced plugs,cleaned spark arrestor,new fuel,new fuel filter/water separator, Checked one way valve on fuel tank, ohm tested the coil,replaced distributor cap and rotor last season,Removed ignition module from the distributor cleaned reapplied dilectric grease,Checked the fuel pressure,,it holds at a constant 30psi underload or idle.
I was told to check the timing,I assume I did it right and assuming my "harbor freight" advanced timing light is accurate,It does look like my timing is off. This engine only has the single mark on the damper and a V groove timing tab. Looks like my manual calls for 8 degrees BTDC at the fixed 600rpm idle,So I turned the knob on the gun to 8,and checked it,,Its not lining up with the timing tab. It also says it should be at 19 degrees BTDC at 1600 RPM and that also doesnt line up.
From what I been reading these engine do not adjust from the old fashioned twist of the distributor,,These need jumper wires,,computers and who knows what else.
Before I go any deeper is there anyway for me to test the module to see if its faulty? Does is sound like it being off would cause the problem I described? Anything else to check? This is fuel injected TBI with about 600hrs. If you need any additional info,Please let me know,,Thanks for the help!
