How did it run last year for you ?-----Sounds like it is running on one cylinder.------Check compression .----Check for strong spark on both leads.----Reed valves checked ?
Sounds like upper and lower shift shaft are not right.---Expensive damage can occur here.-----Hurry to a shop.---They can correct the mistake in just minutes.
Look on the ----aomci------website.----There may be an old gray haired expert in your area that can help.----Also a free ----wanted ----section to help searching for parts.
Well 4 psi will do it.----But the factory diaphragm pressure pumps are ultra reliable and safe.------What is your motor doing / not doing and why are you picking on the fuel pump as the issue ??
Your location ?-----I can not decide whether it is worth fixing for you.----Those 57 Larks are definitely worth saving if there is sentimental value to you.
I would start with a compression test.-----And removal of bypass covers to inspect pistons / rings / look for loose bearings.-----You may not , but I hear noises that can not be fixed with a carburetor rebuild.
What motor ?---- think you need to stop and listen.--------When you put control in FORWARD the prop will turn clockwise looking at the prop from behind the boat.
That is the cut out switch.------Shuts one cylinder down in case of high vacuum ( run away ) condition.-----Rarely causes any problems.----What is your motor doing / not doing ?
