New to the forum and new to boating for the most part. I searched the forum and read a lot of good info, but I could definetly use some help.

First off I purchased my boat last year and everything worked fine. Today was my first time out this year and I got accross the lake and the boat overheated, but the temp. gauge never got past 100.

My first question is what kind of cooling system does my boat have?

Next, what could all be wrong?

And what did I wreck?

I took the thermastat housing apart real quick and noticed that it was completely dry inside. I ran the hose and muffs and did not get any water to drain out of the exhaust.

Please help!!

first off, when was the last time the impellar was replaced, and also you might want to let us know what out drive you have.

I have no idea about the impellar ever being replaced until tonight I had no idea what one was. Im not that familiar with boats, but please dont write me off I am very good with cars. I just need a little education and some time to figure this boat out.

As for the out drive I believe it also says 898 mercruiser. Am I wrong?

I guess I forgot to mention that it has the 305 v8.
