Hey there - Attached is a picture of my 1987 SeaRay engine. I have a few questions that I was hoping you could all help answer: 1) I'm looking at getting a new alternator, voltage regulator, and starter. Any idea how much these parts should cost each? I'm located in Canada. 2) I am looking to get new two new batteries. What should the cranking amps be and should they both be deep cycle/starting batteries? Any brand recommendations? There is a radio and other electronics (lights, wipers etc.) on the boat. 3) I'm trying to find out where the engine serial number is so I can order some new parts. Do you guys mind pointing out where it is? 4) Any good videos on how to change the oil on the engine attached? Thanks in advance!
