I know this has been covered but it’s driving me nuts
3/4 tank of fuel is the max I can get into boat in the water.
1/4 tank of air stuck at the upper section of tank I would think.
It’s a known issue are there any work arounds?
What are you basing the 3/4 on - the fuel gauge or the amount of fuel-burned on the Honda counter? The tank gauge is notoriously inaccurate and I had to replace mine at some point.
If based on burn - what numbers are you seeing? Mine holds about 100G usable fuel, but I rarely take it down below 20G left before I fill up.
Have you checked the vent-line to make sure it’s clear and unobstructed. Had spiders/debris in the vent cap before.
