Damn...she's GOOD! Best Fuel flow system ever!If it’s not more than 5 or 10 gallons per tank fill and somewhere close to the prop curve, I would just go with it and do some checks on the next haul out. Without flowmeters, it’s impossible to tell with these motors on short every weekend bopping around trips to restaurants and beaches. On longer trips you can get pretty close on estimated burn by running regimented segments at constant rpm. My wife is our flowmeter and a genius at this and can get it within a few gallons most days. We run a lot of slow cruising at 1100 and she uses 5 gph, we like to cruise at 2280 and she uses 32 gph as a base and sometimes tweaks it to account for seas, wind against the bridge glass if it’s not open, then throws in a little Kentucky windage based on how the egt is running that day. She uses .6 gph for the gen. She adds it up as we go along and then checks the fill up against her numbers to get a feeling for how happy the engines are or if I need to figure out why we’re burning too much.
My starboard fuel gage is wacky, it never reads correctly and drops faster than the port gauge. Most of my gauges don’t read correctly but they are consistent in their inaccuracy and I can deal with that. So long as the needle is pointing to the same place all the time, that’s all that matters.
Last long trip we were on was when we were up in your neck of the woods. Here’s a shot of the last two full pages of her scrap book on our way home.
