(1) where is the 20 amp fuse inside the cowling?

(2) how do you lock the "tilt up" mechanism so the motor won't tilt up when operated in reverse?

Jim, I have occassionally struggled with this myself. Granted, I probably need to read the manual, but basically when I tilt the engine back down, I pull up again to see if the latch caught. It often doesn't. From their I very unscientifically pivot the the engine from side to side while jiggling the latch. It has always locked after doing this for a moment. Long story short, I don't really have a good solution for you.

But this has thus far worked for me. I really should read the manual to see if there are actual directions.

My 2005 Tohatsu locks *when* you shift into reverse. There is a small rod that moves a block up when you shift into reverse, which in turn locks the tilt mechanism. The little block can be adjusted with an allen wrench.

The manual for our 2005 Nissan discusses the "Reverse Lock for MF and EF type", very poorly. That may be why many of us are having trouble getting the motor to tilt UP when we want it to. If your's is the same, good luck if reading it helps you.

The fuse is in a large yellow box clipped to the block just above the starter switch. There is a spare stored inside. I replaced it and my starter and charging system is working.

I did get the motor locked down last night but don't know how I did it. I put it down and wiggled it around, shifted to reverse and back to neutral prior to starting.

I also can't seem to find the "shallow water operating position" part-way locked up position. I found it once. Anyone know how to get the motor into this position? I'd rather lock it here than all the way up (all the way up, the motor extends far into the fairway and I don't want some power boat to hit it).

Jim as you have found out the tilt operation on the Tohatsu is a pain if you do not modify it and is the only drawback I have found with it. The way to get it in the shallow water poisition is to put the engine in netural or forward and then pull up on it while holding downward pressure on the tilt lever. Now that is a back injury looking for a place to happen. There in is the reason for attaching a small bungy cord to the tilt lever to hold downward pressure on the lever when you tilt the motor up. This in effect will let the lever find the shallow position detent then if you keep pulling up the full up position. You still have to pull the lever up to lower the motor, but a small lanyard attached to the lever and stern rail will take care of this so no bending over while pulling on the engine and therefore less chance of back injuries. You might look on page 24 of the manual which shows the two detent positions.
Here is a picture of my first set up to hold it down. I have since changed the spring to a small bungy.

Jim, I was in San diego while you were attempting to race

The 06 should lock down in reverse and neutral from the factory. It is pretty easy to see what makes this happen. I changed the factory setting to only lock down during reverse. It is described in the instructions.

Tilting is the real bane of this motor.

The half up shallow water mode is blocked by a spring(removable)

The lock that holds the engine up needs upwards pressure to keep the motor up. (spring-bungee)

I love this engine BTW.

Tom.

Frog detailed the best solution to the problem, and BTW:
"...shifted to reverse and back to neutral prior to starting."
Never, EVER, shift the transmission cold; shift ONLY while the engine is running. I think that admonition is in the manual.

I am getting my 06' Tohatsu any day now and was wondering if my Garhauer 2 spring bracket will be enough to lift the motor up easily. I currently have a Johnson 9.9, 2-stroke Sailmaster on my Catalina 25 and can lift that motor pretty easily.

my 2 spring mount is enough. It is 93 lbs that is just a little more than my previous motor.

I am finally getting the tilt to operate right, when you are looking for that part way up position, tilt it up, bring it back down with pressure on the lever, then when you feel the big click just as it drops into the lower position, raise it up about 2 inches with pressure on the level and it will drop into the part way position every time.

It seems hard to shift from reverse into neutral, do you find you need to go to forwad for a second?

Also my system battery voltage comes up to 14.4 this could overcharge my gells. Anyone using a voltage limiter or how about a big switch to switch off charging? I want to limit it to 14.1 - I guess I could switch on some inside lights.

Okay, you've all convinced me...If my outboard ever gives up the ghost, I'll buy a Mercury.

Don't take this as bashing of the motor. What I love about the motor:

(1) very easy starting either electric or manual. One pull.
(2) super quiet at idle and also when running 1/2 throttle or more. I can hear the CD player! MUCH quieter than the Honda.
(3) plenty of thrust forward and reverse.
(4) super long shaft - no more pulling the prop!
(5) full hull speed at 1/4 throttle, lots of reserve power, cuts through kelp nicely.
(6) very ample charging circuit produces useable power even at low RPM
(7) relative light weight - 93 lbs - for all this.
(8) Low price.

I've got the tilting all worked out, no more problems, just takes getting used to. No complaints.

Shifting to neutral out of reverse is taking some getting used to, it will probably break in smoother, maybe I'll drop the idle speed a tad.

Jim,

First, being a very happy Merc owner, I am somewhat biased in my opinion of Mercury outboards, but with that being said, I believe that virtually all the points you listed above could easily apply to any modern 4-stroke whether it be a Nissan, Tohatsu, Yamaha, Honda, and yes, even a Mercury.

With the Tohatsu and Mercury sharing the same powerhead, I'd imagine they would run about the same, but the Mercury outboards have a couple of unique and, to me, rather significant advantages...

First, no tilt lever...just grab the cowling and tilt. To release, just tilt it a little more and drop it down. It doesn't get easier than that.

Second, the integrated throttle/shifter that does away with the shift lever. This is the greatest thing since sliced bread and worth its weight in gold!

(Oh, did I mention the Merc 9.9 weighs 84lbs?)

Received my new Tohatsu 8.9XLS this week. 4 days shipping to
Calif! I love the motor. BTW the Tohasu-Nissan-Mercury
9.8 are identical except for the decals, so you Mercury
people are paying for the name. As an additional benefit,
I cut up the 3" thick styrofoam packing panels, and used
it to insulate the outside of my built-in icebox. Tough
to reach - I duct taped the pieces in place. Also glued
a 3" X 8" X 15" piece to the inside of the lid. Hope it helps.

Oh really???

Does the Tohatsu/Nissan motor have an integrated throttle/shifter on the tiller (no shift lever)? Does it have a no-lever tilt function? Is it available in two different gear ratios?...Hmmm, I'm thinking not.

Athough their website doesn't say, I would think that 84 lbs is probably the weight of the short shaft.
