Hi guys new to the forum and have a question on this outboard engine i just had fixed that was sitting for probably 2yrs before i bought the boat its on....needed a distributor first and i repaired it due to no fire issue. It wouldn't pump water after getting it started so i had waterpump, and all carbs&floats and fuel lines redone. Put it in water yesterday and boat has no fuel tank so i used a portable tank w/bulb. Idles nicely and after going in gear throttle gets little response. After checking all my wires and all everything is good. Had my buddy with me and we had throttl forward i figured imma pump bulb make sure fuels getting through. The boat picked up and ran like a scolded dog but its only while i constantly pump bulb then about 4k rpm the bulbs outta fuel and i just keep pumping it keeps going till boggs out at 5k and above. Is this tanks fuel line to small or the cap not loose enough for the engine to keep sucking what it needs? Im not sure if there was electric fuel pumps on the inboard tanks? Any help appreciated thanks guys.
