You should follow the manufactures recommendation....oh and nobody has an opinion on oil, (ever).

So the 9.9 Tohatsu arrived in good condition. I was planning on breaking it in on conventional oil and maybe switching to a full synthetic. Any recommendations? Curious about your thoughts?

When we bought a new car a couple years ago the dealer advised to run regular oil or an oil/synthetic blend for the first 10K miles to break the motor in. After 10K they advised it would be OK to run full synthetic.
Thank you all for your comments and experiences. I think I will go with the Tohatsu 9.9. I will post again on this topic when I test it out. All the best.
Most modern engines start easily on the first or second pull. IMO electric start is only especially valuable for people with physical weakness or disability. For them it is undoubtedly a blessing. Tohatsu engines are generally easy starters.

A different twist on Steve's wording is that it also depends on how the boat is used. If you mostly single hand or sail with the Admiral, you may not highly value electric start, but if a situation arose where the Admiral had to start the boat unaided or wanted herself to sail single-handed, you might value electric start a bit differently.
Another consideration, and I don’t know how this applies to Tohatsu products, is that some outboards only have alternators if they have electric starters. That said, I was fairly able-bodied when we had our C-25, but I appreciated not having to reach down over the transom and under the pushpit to pull a starter rope, which I did with the motor that came with the boat. The push-button on the replacement was really, really nice. But we also loved our roller-furler, and we weren’t racers—we were wimpy day-sailors who slept aboard occasionally. Different strokes...

The Tohatsu 8 HP Outboard Motor model # MFS8BEFL has both electric and pull start. It weighs 90 lbs. It's probably the smallest electric start available.

I'm leaning towards a Tohatsu 6hp but it's not available with electric start. I don't particularly want a bigger motor, more weight. Any ideas?
According to the Tohatsu site, their 6, 9.8, and 9.9 all come in 25" "transom height" versions, while the 8 does not. The 8 and the 9.8 are the same displacement (209 cc) and weight (81 lbs.). The 9.9, with EFI, is bigger (333 cc) and heavier (95 lbs.). So if you want electric start and fairly light weight, the 9.8 might be best. If you don't care about electric start, want light weight, and don't run in "big water" or heavy conditions, the 6 could be good. But I'd suggest 25" in just about any case, so I'd rule the 8 out. And because I mounted and removed mine just once a season in a boatyard, my Honda's weight (107#) wasn't a concern.

The Tohatsu 9.8 is for some reason no longer offered in the ultra long 25" version. The Tohatsu web site still shows it but If you call around like online outboards they will tell you nope, sorry.

With our Tohatsu, the only reason we opted for electric start is because it included an alternator to charge batteries. How often do we use the electric start? Rarely. When we have not used the engine for a while we will use electric start, but when we are using the boat once a week or more we use pull start as it starts first or second pull.

Used the new Tohatsu 9.9 efi for the first time. Electric start is nice, but I was mostly after the alternator. I have had some skin end up on the traveler cleat starting the old motor in a panic. Electric start could have prevented that. The new motor seems to run pretty smooth and has a lot of thrust. Aside for a slight rattle at certain rpms coming from the trim mechanism it is super quiet. We keep a lot of weight on board and we're doing over 5 knts at 1/4 throttle with a not so clean bottom. Awesome. Can't wait to go on a short passage. And the extra weight over the old 8hp 2stroke is surprisingly OK with a 3 spring mount.
Ken I'm curious with the EFI do you still have to pump the primer bulb? Without a carb bowl to fill and the EFI not being vented like a carb is the fuel would always hold it's prime? Maybe??

Mine is a much bigger EFI motor, but often goes a few weeks between uses. Like a car, I have no bulb to squeeze, and starting is always within very few revolutions. As you pointed out, there's no bowl to go dry. It might take more turns after a winter on the hard, but only my mechanic would know. I would still always stabilize the fuel, and "running the motor dry" might be a more debatable strategy, especially with a stabilizer.

I wonder if carburetors on outboard motors have a drain screw in the bottom of the carb bowl, like many lawn mowers and snow blowers. Has anyone ever looked? Draining the gas out of the carb bowl would seem to be a good way to winterize the motor. If you run the engine until it stops and then drain the carb bowl, I can't think why you'd have to add a stabilizer.

Steve, Yes they have drain screws and is what I open to get the last bit of gas out when I winterize. Same with my snowblower, lawnmower etc. I open it, let the gas drain out then spray carb cleaner in to rinse out any sediment that might be in the bowl.

From Tohatsu in response to my e-mail query: "We recently dropped the 25" shaft from the MFS9.8 line-up and replaced it with our new MFS9.9 EFI model. I will inform our marketing dept. that the website still incorrectly lists the 25" shaft."

Thanks Scott. That's good to know. That's what I'll do in the future.

Too bad that Tohatsu is dropping the 25 inch version of the 9.8 as it weighs over 10 lb. LESS than the 9.9 its being replaced with. Way back when, one of the reasons I went with the Tohatsu vs Mercury (also made by Tohatsu) Yamaha or Honda -- was weight. 10 lb. may not sound like much, but when the weather sours requiring the engine being lowered (or raised) or when removing/putting back on the engine mount, etc., every ounce, IMHO, counts.

Actually, FWIW -- comparing 9.9 hp 25 inch shaft engines, the Tohatsu has gone from being the lightest to upper mid pack in weight and is now one of the more expensive engines. I would take a hard look at the Mercury which is now the least expensive and lower weight option for elect start/tiller configuration.
Peter Bigelow C-25 TR/FK #2092 Limerick Rowayton, Ct Port Captain: Rowayton/Norwalk/Darien CT
Mercury has added the (Tohatsu) 9.9 EFI model, so it's possible they will be dropping (or have already dropped) the 25" carburator version as did Tohatsu. EFI is a breakthrough in this category--hopefully it will enhance reliability in the face of ethanol and the other things that threaten the tiny idle jets in small-engine carburators--generally at the worst possible times for sailors.
For people who want light weight and reliability with ample power, here's a thought: Put a bracket on each side of the transom, mount two Tohatsu 6 hp 25" motors on them, and mount remote throttle/shift controls on the sides of both cockpit seats. You get up to 12 hp, twin-screw maneuverability (to move virtually sideways or pivot in place), redundant power, and ease of lifting on and off the brackets. (And what a look! Like having four exhaust pipes on your Prius! )

Thank you all for your experience and knowledge. I think I will go with the Tohatsu 9.9, 25" shaft, alt, elec. start. I will have to change my bracket, but the upgrade will be worth it. I hate outboard motors, but need one to get in and out of my slip.
