H260...Rebuild Tohatsu or new yamaha 9.9?

[LarryH]

I had some work done to my Tohatsu 9.9 to fix a spun prop and we replaced it with a 4 blade. The boats not quite as fast but i seem to have more control at idle speed for docking which i like very much. The engine is running better then ever in the 2 years i have owned my H260 but if had my troubles with it over time.

However, when i crank the engine full throttle, the tohatsu is very loud and we cant barely talk in the cockpit and the engine seems like its giving its all to keep us moving along.

Its time to pull the boat from the marina to get some other work done, I going to have the Tohatsu gone through, repainted, tuned up, impellar replaced, etc. However im thinking why not just put a new Yamaha 9.9 with powertilt on the back. I have the $$$ and I just dont trust the Tohatsu as I think its original to the boat (1999).

Can anyone give me a report on their Yahama? Is it loud as well? Does it push the boat with ease or is it a struggle? Is this the best engine for the H260?

Thanks

Larry

I could be wrong but I believe the yamaha and the nissan motors are built with tohatsu parts. I recently got rid of my 9.9 two stroke tohatsu for a 9.9 four stroke tohatsu with alt and electric start. Its very quiet and opted for the power prop as well I do notice more hull speed with less rms with the four blade prop hence its a quieter ride. Not sure where you are but got my motor 2011 for $1700.00 up here in northern ny

You may want to also ask on the boating forums at iboats.com, which seem to get a lot of outboard posts. There's a forum area for Tohatsu/Nissan, and it also covers Honda, where I get a lot of help.

Four stroke engines generally are quieter using less fuel. They are heavier than the 2 stroke eingines. It is correct that you will find Tohatsu parts in Honda but they will not admit it. If trailering with the motor on the back end of the boat, make sure that you tie it up to keep it from bouncing gioing down the road. I always suggest letting the fuel run out to help prevent the carb being clogged as straight gas will also congeal as well clogging up the jets inside the carb.

I have a 2004 8hp yamaha high thrust, long shaft 4 stroke with elec tilt, alt, and pedestal controls on our 2004 H260. Used it for 6yrs and it's been a flawless mate for this boat. The new yama 9hp are the same size/wt/dimension but have somehow magically tweaked a bit more hp. It's irrelevant as the 8hp pushes the boat to hull speed (6kts) at about 80% throttle and burns about 1/2gal hr.

It'll digest ethanol just fine and although I'm a maintenance kook I'd say it'll last close to 1000hrs between replacement with care. It's fairly quiet and talking underway has never been an issue, but my wife will talk through anything.....just kidding

Buy the new OB but don't think that bigger is better. HP has a limit on a displacement hull and weight at the stern is always a concern. And I'll 2nd what CDC said, always tie your OB down when trailering and run it dry if it's not being used for more than 30days.

Yamaha is nice

I have the same 8hp high thrust, with electric tilt and start. It is on my 2005 H25. It easily acheives hull speed at a little over half throttle. It is very quiet. It also puts out over 14 volts to the battery at just over idle. Mine has been flawless. The 8 and 10 yamaha are the same size and weight, the 10 just has a longer stroke. The 8 is plenty. I've done zero maintenance on mine since it was new in 2005. Just add fuel and go.

I had the Yamaha 9.9 4 stroke high thrust for several years. It was great for powering through the large wakes I encountered on the 45 min motor to my sailing grounds.

I've yet to hang an outboard on the stern that allowed for normal conversations at max throttle. My wife always sighs with relief whenever the outboard is shut down, regardless of the power setting or time the motor was on. She loves the sound of wind in sail.
