ETTY Posted October 14, 2006 Share Posted October 14, 2006 I have "heard" that Honda Outboards (even with their advanced corrosion protection that the company loves to sell it's product by) corrode quite badly in the salt water. I have been given examples like "they are like a disprin in water." Can anyone fill me in on their experiences with them and either confirm or deny these rumors as I believe they a truly fantastic engine and I am seriously thinking to buy one of these for my next outboard. I was truly horrified at this!!! Link to comment Share on other sites More sharing options...
njsconst Posted October 14, 2006 Share Posted October 14, 2006 Save yourself the heart ache and just get a real outboard. Honda should stick to building lawn mowers! Just get a Yamaha - tried and tested to be the Best! Link to comment Share on other sites More sharing options...
Flightmanager Posted October 14, 2006 Share Posted October 14, 2006 You can either believe this or not , Im still undecided myself , but a certain reputable dealer of non Japanese engines explained to me that the Japanese are using a lot more copper in the alloy mix for the blocks , as it reduces the cost of manufacture. He was of the opinion that after about 6-8 years of service life , that the internal corrosion level would be quite high , probably to the point of catastrophic failure. So far , I have not heard of any Japanese motors suffering from such a thing , perhaps time will tell. Ross Link to comment Share on other sites More sharing options...
Guest Big-Banana Posted October 14, 2006 Share Posted October 14, 2006 I heard the same thing when we were in the market to buy an outboard. The boat we tested had a 150 and it was sluggish and pretty average, so that made our mind up. But there was a stall in the states which showcased a cut out motor, saying if you want to buy a outboard that corrodes buy a Honda. Link to comment Share on other sites More sharing options...

The problem is it was only true up until the early 1980's when the Japanese manufacturers responded and lowered the copper content of the alloy. Its amazing how the bad name can still stick after all that time. Perhaps not so amazing since the comment came from a rival dealer. Link to comment Share on other sites More sharing options...
tuffy Posted October 15, 2006 Share Posted October 15, 2006 I've had my Honda 40 for 2.5 years and the only prob EVER encountered was a dropped split pin in the throttle connection once which was fixed on the water with a long shank 1/0. There is not an ounce of corrosion on the motor and I've probably done about 300 hrs on it. FLUSHED THOROUGHLY AFTER EVERY TRIP - that's the secret, and sprayed under the cover with Inox about once a month. Beautiful quiet donk and very economical, but if ever I was to change brands I would go Yammie - equally as good. Link to comment Share on other sites More sharing options...
Flightmanager Posted October 15, 2006 Share Posted October 15, 2006 Well there you go , I only got half the story !! Surely , you would think that a large manufacturer of outboards would be interested not only in the performance of their engines , but the longevity as well ! My outboard is 30 years old , and still runs well . One would hope that the Japanese engines , with a bit of common sense care , will last just as long . ross Link to comment Share on other sites More sharing options...
ETTY Posted October 16, 2006 Author Share Posted October 16, 2006 Thanks for clearing it up as I believe they are truly revolutionary engines and for a corrosion problem to let them down would be devistating to their mechanical engineering. Thanks ETTY Link to comment Share on other sites More sharing options...

Hello all, my 2 cents worth comes via a marine mechanic who happened to be working on a late model yammie when i asked or more appropriately suggested that yammies where a good engine. The mechanic replied dispondently that the only good yammies are the salt water series when i asked him why he explained very quietly that the blocks on yammies are to thin otherwise they would be an awsome engine.
