honda99I have a 9.9 Honda that is 7 years old. Never a problem with it. Had it out a couple times this spring. took it out and it ran for about 30 seconds and shut down. Restarted and same thing. Looked and no waterPortable, fuel efficient, and powerful. The BF8 and BF9.9 offer more of what you want. More battery charging power. Easier to use features.
