Guys my original 1987 OMC engi
Guys my original 1987 OMC engine block got cracked.I got older 1980 OMC 3 liter.Got engine block swapped.Engine is running good.When i am running at slow speed it is ok.But when i am trying to run faster like 10MPH+ i can hear some knocking or clicking sound coming from engine.I dont know if it is from piston or carburator or from somewhere else.Does any1 have any idea.
Also engine for running fine for few hour.But after that it suddenly started slowing .I dont really dont know how to explain.Like when ur about to to finish gas in car it acts crazy.Same things started in my boat and it stopped some times.When i give some choke and start it starts and after some time it runns wiredly and stops.My boat fuel tank was less then quarter left.Is it possible some dirt went in carburator and that is why it is doing like thing.Also i opened fuel pump uper cover for fuel filter and i dont see any fuel fiter installed.so is fuel filter necessary.Please let me know.thank you
Also can any1 tell me what type of engine oil it need.The manual for 1987 OMC says SAE-30.But mechanic told me SAE 30 dosent have detergent & gave me Merucry SAE 25W40 oil.So is it ok.let me know.thx
