Short version:
Does anyone know what the flow rate (gal/min or whatever) of the water pump on a '90 125HP once warmed up at idle? I believe that the water pump is pretty generic, so I suspect that any of the V4's or V6's Johnsons/Evinrudes in that era would be representative.
Long version:
Came into a boat that had been sitting idle on a lift for 6 years. Fixed some wiring, bypassed the gunked up fuel system, rebuilt the carbs and now it runs pretty decently. Took it out and got it up to WOT and had it running for about the lake for 15 minutes without issue.
My concern is the impellor / water pump. I see the advice to rebuild the water pump on a motor that's been sitting around for a while. Unfortunately, I don't have any way to drop the lower unit without building a platform in the lake, I don't own a trailer, and I don't really have a place on land to work on the boat. First option is not really viable, but while I'm sorting out 2&3, I'd still like to tool around in the boat.
Water seems to be coming out fine from the pee hole, but I don't know what the baseline should look like. Boat was decently maintained before being marooned on the lift and it's always been in fresh water. I'm willing to take my chances for a few weekends if I think the water flow rate is something close to normal.
Does anyone have the baseline flow rate? I was thinking that I could calibrate against that with a gallon jug once warmed up at idle.
Any suggestions gratefully appreciated. (and yes I am going to replace the pump in the near future!)
