I am new to this and I just purchased a bayliner capri with a 2.3l engine. I dont know anything about these type of boats I have only owned boats with outboards. I am not sure if engine is any good sometimes when I try to start it it will turn over other times I cant even turn it over by hand. I was wondering if anyone had any suggestions and if motor is bad can I swap out motor with any 2.3l engine or even a v 8?
