Ok, I am not new to boats although i am somewhat new to engines, I am younger but I have been boating my whole life, and i have a basic knowledge of most boats. I have a 87 25.5 Century Mirada with a 305 chevy small block im pretty sure. It was my fathers boat but hasnt been in the water or started for about 3 years i dont think... he was about to start working on it again but he recently just passed away
The whole boat has electric power and the batteries are still putting out decent juice (going to replace both of them anyway) but when I turn the key to start the boat all i get is like a loud grinding kinda noise... really hard to explain.. i pulled the starter and had it looked at, its spinning perfect and the teeth are still in good shape... so i put the starter back on and cleaned the battery terminals (thinking it wasnt getting enough juice) but still the same noise... it does get any further then that what I turn the key, just a loud clicking/grinding noise... I already pulled the spark plugs so there isnt much compresssion. and i can also turn the engine with a rachet so this means its not seized up correct?
I remember my father telling me he didnt winterize the boat but he had a "heater" in the engine compartment on cold nights... but i think that was a lie...
how can i tell if the engine is junk or whats the next step to look for? hoping to get a mechanic to come out and look at it soon
Thanks guys -adam
