Today, I purchased a 1997 Glastron SE175 with a V6 4.3L Volvo Penta. This is my first boat and needless to say, Im very excited. I had a mechanic test out the engine/outdrive and he says pretty much everything is in order.<br /><br />However, Id like to buy a good repair manual so that I can do basic things. For example, the mechanic suggested I change the gaskets on the risers. Which book would be the best for these types of things? OEM or aftermarket?<br /><br />I searched the forum, but did not find a definitive answer. Thanks in advance!
