No issues after over 100 hours of use on my 15' x 60'' wide jon boat. Only issue I had is some kind of insect built a mud home in my gas overflow line that comes out beside the water output line. This caused overflow gas to flow into the crankcase making the oil level high. Easy fix, with a call to my local Honda dealer, with about 10 minutes of my time. Highly recommended because it is light, powerful and so quiet that I fish most of the time with it running.

I have had a Honda BF15A since 1998, it has never let me down, runs on the smell of an oily rag and starts after months of non use first pull. ! Parts easy to get and I would buy one again in a heartbeat.

Replaced my 25hp 2 stroke Johnson on my 3.9m Stacer. The Honda is obviously quieter being 4 stroke but the performance, quality and fuel consumption are exception and with a 5 year warrenty this is a great buy. You can actually have a conversation in the boat even at top speed. The gas lift assist is great but maybe should have got a power lift.
Just about everything...
Probably should have got the power lift instead of the gas lift
