I visited www.onlineoutboards.org, since my old engine has been unreliable, and see that for 2007 Tohatsu has an 25" 6 hp engine, weighing in at 55 lbs. It is one cylinder, rather than the two cylinder that the 9.8 hp engine is, so there is now a choice. I think 6 hp would work for me, but I wonder what are the downsides of the one cylinder. Is a one cylinder as reliable as a two? Anyone have any opinion on this option?

Hi

I have a single cylinder Honda 5hp. I've had it from new (it's now 3) and it's been very reliable. You probably lose a little smoothness in running from twin cylinder.

I bought the 6 HP 25" shaft and like it. Granted, it's not as smooth or quiet as a two-banger, but it's adequate for our sailing area (inland Lake). It won't pull a water skiier around the lake but it will push my boat at 5+ kts. Also, it was much lighter than a two cylinder, cost less and I easily wired the charger to my battery. I can't speak to reliability as i haven't had it that long, but it runs great.

the only difference is weight (less) and vibration (slightly more). Go for it, 6 HP is plenty, even in the ocean, unless you have huge tidal currents, or other demands for high HP.

One of the boats in Fleet 7 has a 5 HP Mercury single cylinder and goes everywhere we go.

That said I love my 9.8 Tohatsu.

We got caught out in some strong wind (25kts+) a couple weekends ago towing the kayaks and had a hard time getting to an anchorage with our 4.5HP with bare poles. I think I'll be putting a 6 HP on Swimmer next season. Plus, having another way to charge the battery wouldn't be a bad thing.
