"I got two 91 150's looper

"I got two 91 150's loopers, port side not smoking that much at idle. starboad smoking like its 50 too 1. Anyway too make the port run more rich so it can smoke more like the starboard, how am I gunna do that? People told me to cap em and mix it in the fuel tank buts thats a headache!! The sound alarm came on today constantly until I started the motor and the sound went away..... IS this indicated a lack of flow to the vro pump? and thus not making the boat to start ? OR just something TOTALLY different? The sound alarm I thought was overheat temp sensor activated. I dont know really. I need advice."
 
"The service and users manuals

"The service and users manuals are not clear on this issue. I have a 1988, 90hp and kept getting the alarms. The shop said it meant VRO was not getting oil. I disconnected the VRO wiring and now add oil which I trust more on an older model. Overtemp also alarms but one is pulse and one is continuous."
 
"I would first check the engin

"I would first check the engine temp, are they running at the same operating temp?
Then clean out the oil tanks, lines and filters.
If You swap the pumps does the smoking moove to he other engine?"
