automotive engine rebuild kit verses marine kit

[tbone47129]

What is the difference between an auto engine rebuild kit and a marine engine rebuild kit? Besides the brass freeze out plugs.I have never rebuilt a marine engine before.I was just wondering if it would work.

This topic has been discussed earlier on these forums, try the search.<br /><br />Bottom line is, that automotive and marine uses differ in a number of ways hence making the manufacturers change details here and there. <br /><br />Especially electrics, cooling and fuel systems.<br /><br />Although some components are still the same, many boaters have tried a direct swap and had problems with performance and much more.<br /><br />Generally, a DYI conversion ends up in higher price than a 'born' marine engine - especially when you consider the quality.

Hee, hee...What's the matter Tallman? Ya feel this topic has been around the block a time or two already? At least he didn't ask why everyone always bashes Bayliners...<br /><br />TBONE...<br /><br />The issue you bring up is a fairly common topic of discussion in here... It's a very good question. What ARE the differences between an automotive and marine inboard engine? Try as UU suggests, and do a search on the topic. If you still have questions...please don't hesitate to ask. I think you'll soon discover there are some varied opinions on this subject. However, once you recognize those who are truly "in the know" re: marine engines vs. those who simply have a strong opinion...I believe you'll be convinced that many, many important differences do exist between the two powerplants.<br /><br />Walt

Aside from the obvious dollars and cents involved in the cost..... <br /><br />Check with your local NAPA. Napa sells rebuild kits, pistons, gaskets (darn near everything related) and all listed in the marine book.<br /><br />There are differances in the bearings and gaskets. Everything is designed for prolonged WOT. Yes freeze plugs are differant too.<br /><br />Check NAPA , check the web and shop for your best deal. Best way to save money is to do it right the first time. <br /><br />Bob

You know I had to reply to this one. Don't have a cow, I am not going to start. tbone47129 you will have to do a search on my name to find out my opinion. All I can say is when you have done all your research on what you want to buy. Call (also has a web site) Northern auto parts. Tell them what you want and see how much you save. No disrespect but I have always found NAPA to be over priced.
