Hello all. Most of us who have this great engine are a little PO-ed about the tilt setup. I figured out one of the problems yesterday. The lock that keeps the motor in the water has 2 settings. The way mine came from the factory locks the motor in neutral and reverse. which meant I had to shift it to fwd to tilt. I do not like this as I like to leave the engine ready for an instant resart. Choke on, and in neutral.

If you move the lock lever to the other hole, it now only locks in reverse!!!!! There is a little rubber keeper that holds the linkage in place that was a PITA to take apart. I did it from the dinghy lying on my back, waiting for the engine to come crashing down!!!

The tilt support arm is another story, but I suspect equally easy to "fix". I was thinking that a spring might be all it needs to "default" to one position. The obvious position would be the tilted. If it was spring loaded to the down position, a wave or wake could have your engine suddenly dropping. It was defaulted to up, you could at least raise the motor with one hand and it would stay.

I will look again at the mechanism, but I think a spring would do it.

More to follow.

Tom.

Tom,

I was working on a rototiller yesterday that used a cable within a cable to change engine speeds. It occurred to me that the same mechanism could be adapted to enable the tilt on our Nissans. Will go to the lawnmower shops today and pick up one.

Tom , any new info on the spring project? I'm thinking of going ahead with using a motor control cable to ease the tilt problem. The project is on hold since the boats at the marina and the motor is in the shed.

I'm in the dark about the rubber thingy that you adjusted to have a reverse only tilt. Are you talking about the black rectangular unit on the shift rod? Seems to me adjusting that would give a reverse only configuration.

I am refering to the pg 27 Para 8.3 on the manual that can be found here.

http://nissanmarine.com/tech_talk/pdf_files/Nis_8A_98A_4str.pdf

It talks about "locking the shift lever" which must be a lost in translation thing. My motor shipped with the lever in the b position that locked the motor down in neutral and reverse. I moved it to (a) position and now it only locks in reverse.

I have not messed with the spring yet. It is on the list though.

On page 24 of the Nissan Marine Owner’s Operating Manual you will find section 5-6 Tilt up, tilt down. The very first item is a prominent warning which states: “When tilting up or down, be careful not to place your hand between the swivel bracket and the clamp bracket. Be sure to tilt the motor down slowly.”

Now consider this. Why would a hand be even close to that area? Why of course to work the tilt lever while also tilting or untilting the motor. So Nissan recognizes a danger inherent to their design.

I recognize that the Nissan design should pose little problem with the shorter shaft models on low transoms but let’s face it. The ultra-long shaft version is designed for high transom boats such as the Catalina 25.

Let’s look at the actual tilting/untilting procedure with two different motors, my old Honda 8 and the new Nissan 9.8.

Honda 8
Tilting Up
1. Reach down and flip the lever forward. Remove hand and use it to grasp pulpit.
2. Reach other hand down and tilt motor while enjoying little clicking sounds as ratchet engages during upward travel
Tilting Down
1. Reach down and flip the tilt lever back. Remove hand and use it to grasp pulpit.
2. Use other hand (or both hands) to lower motor.

Nissan 9.8
Tilting Up
1. With shift in neutral or forward, reach down with right hand and tilt motor all the way up. DO NOT LET GO.
2. Reach down with left hand and lower tilt lever to lock position, then slowly lower motor against lock. Make notation to schedule appointment with chiropractor.
Tilting Down
1. Use right hand to pull motor toward you. HOLD IT THERE.
2. Reach down with left hand and pull tilt lever toward you and hold it there while you lower motor with right hand. Do not forget appointment with chiropractor.

Working over or through the pulpit on a Catalina 25 is never easy and you can develop back problems (or make existing ones worse). Having to use both hands as described with the Nissan 9.8 can make you end up walking like a troll.

I am sure Nissan saved a few dollars/yen with this design but how I long for a nice Honda-type die-cast two-position ratchet control.

Anyone have a fix yet?

To tilt my Mercury, I simply grab the cowling and pull until it clicks at max tilt. To lower, lift a little until it clicks, then lower away.

Aren't Nissan and Mercury outboards made by Tohatsu? It would seem that they would share many traits like the tilt mechanism, but I guess not.

My daughter is 8. No such luck with boyfriends (thank god!)

The Merc mount is completely different from the Nissan/tohatsu.

Without "modifying" the engine, it looks like a small torsion spring could be put on the tilt-rod allowing it to default to either up, or down. That looks like the best I can figure out.
