Hard Starting Tohatsu M115A

[tablerockboater]

I've owned boats 53 years.
New-to-us boat and motor, just getting used to it. Run maybe a couple of hours.
Battery is good. Gas is fresh.
Squeeze bulb, move fast idle lever, choke, crank . . . crank . . . crank.
Nothing.
Then, starts and runs great.
Same thing every time.
Don't know why it doesn't start. Don't know why it starts.
Flooded?
No gas?
No spark?

First try to figure out why it's not starting. When it won't start, first check for spark. If it has spark, next shoot a little fuel or starting fluid into the intake and see if it then starts right way. If yes then you likely have a fuel issue. Also check the compression.

If "my son" accidentally reversed the terminals when he connected the new battery, and now there's no juice at all, where should I be looking for the fuse designed for that error? There is no inline fuse, and no fuse box, the 1995 Hurricane manual saying the "fuses are near each switch". Thanks

There is a fuse wire.

I forgot about this, but I'm happy to report I found the "junction box" on the right side of the engine. Under it I found the main fuse that had blown, and the spare, wrapped in a heavy plastic. Things were so clean there that the last time anyone had been there was in the factory in Japan in 1994.

Your cold choke may need some work to start instantly when engine is cold.
Does is start quicker after a warm up ?
