My buddy and I am at "Wits End" on this 115 Johnson.
The boat has sit inside for 4-5 years-before that the alarm had been going off indicating oil/VRO pump problem.
Fast foward=New VRO, all 4 carbs rebuilt, new tank pick up pipe, 2 new fuel pump up bulbs, in-line fuel filter.
Last repairs, we went into the new VRO assembly==Had a tan, Coffee with creme color, with some light grit on the air motor side of the VRO. The fuel and oil side of the VRO pump seemed clean with fuel/oil.
Had it out today, and it would idle a lot better, and would run fine up to around 2700RPM, and then just lay down flat. The Stratos boat would not come up on plane unless the choke/primer switch was held in.
On the last VRO repairs, the vacuum pulse valve also had that same tan "Mud/Grit" in it??
Does it sound likely that a headgasket O ring could be leaking into the crankcase and pushing pressure instead of vacuum on the pulse valve/spark arrestor???
Our next step is to pull down the VRO=AGAIN= to see if that same "Mud" looking stuff is in the vacuum source to the VRO???
We would thank you all for help...Bill.
