Fighting Outboard Motor Build Up with Bulk Mercury Optimax Oil

Within the first year of owning our outboard motor, it started to slow down a bit. It wasn’t anything major, and it was still functioning well, but I couldn’t help but feel like we were losing a lot more performance in the first year than was typical. When I told my husband my thought, he started to notice that small shift, too, and said it was too early on for this.
His best friend from his childhood is a mechanic, which has saved us a lot of repair money for our vehicles over the years. He looked at the engine and said we had a bit of a carbon build-up and should have been buying bulk mercury Optimax oil this whole time. Luckily we caught it early on and our engine has been running much better ever since.
