I had the top end rebuilt on my 525EFI 2 winters ago and they put my intake manifold into a parts washer and some of the 525 decal came off. I have seen this on a lot of 525s and never knew why it happened, but it all makes sense now.

There is another thread where they posted the picture of the decal, do people just get these printed at a vinyl shop? or is there a place to buy replacements that are easy to put on? Anyone done this before that has any tips for me?

Thanks in advance!

well shoot. I might have just found one. https://www.outboarddecals.com/mercu...ine-decal.aspx

Will still take any advice on how to replace it if anyone has experience.

Glad you found one, curious how many hours on your 525 and did they find any issues when opened up? I have 245hrs on mine and never opened, juts serviced by the book.

I have a friend who had his airbrushed on, then clear coated and it looked great. He removed the aluminum panel and reglued it once the airbrush job was done.

the engine had 400 hours on it, but it was never really road all that hard for the 400 of those hours. left stock and just basic maintenance every year. When we tore it down there were no issues with the valve spring pressure, but some of the rollers on the rocker arms were a little rough/sticky which is usually what blows up on these engines and sends needle bearings throughout the whole engine and then it more than just a top end. When talking with some other engine builders they mentioned the head gasket on these breaking apart and the metal ring of the gasket that seals off the piston bore will "walk" and rub into the block. If that happens you have to resurface the block and its more than just a top end at that point also. There was a small bit of oil consumption due to valve seats, but overall still a decently solid engine. Now she is running like a champ.
