Re: OMC Stern Drive Stringer Tilt

Ayuh,... I'm Surprized it Works at All,... You're Lucky....

That is Only a Tilt system,.. No Trim...

It goes Down, faster than Up, because Gravity is helping it Down,+ it has to fight the Weight going Up...

Re: OMC Stern Drive Stringer Tilt

Per your vid, the operation is perfectly normal. It is still three times faster, going up, than the hydraulic black anchors (Mercs, etc)

If you are new to the boat, three pieces of advice. One, never run the OD straight down to stop. Learn when you are near the bottom, then 'bump' it the rest of the way to stop. Otherwize you will end up blowing the sector shaft right out into the briney deep.

The second is, never use the tilt as a trim. Only in emergency shallow water situations should you ever run, no more than, about 15-20% up tilt to get the boat into deeper water. Your ball gears should never go beyond about 1/4 wear. If so, replace them.

Third; due to the age of the outfit, and my assumption that the tilt motor gets very little attention tucked way down where it is, I would pull the motor and check for cleanliness, brush wear and commutator clarity. It is not uncommon that for the tilt gearcase to take on water. This works it's way up the shaft and into the motor. There are little tricks to keep/reduce this from happening. Let me know if you are interested in them.

Your tilt motor is held on by two long thru bolts. When you remove them the motor end plates will come loose, so hold onto them as you extract the motor; especially the back plate with the brushes and wiring.

Ayuh,....This Is a new to Badman boat...
And,...
We've been waiting for You to come around with your intimate knowledge of the OMC Stringer drives...

Please click on Badman's name,+ see his posts(his 4 or 5 threads, Good pictures),....
Badman has a pretty unique old barge, with unknown origins.....
It seems to be a early/ mid-60s British creation...
I've been trying to help out abit, but am Lost with OMCs....

Re: OMC Stern Drive Stringer Tilt

I checked out badmans posts, Bondo. Got a kick out of the Napoleanic bow rail on this little critter.

If he gets it floating, it'll be a pretty unique item. Well at least from the Yank perspective.

Hey WizeOne, tell us more about Stringers. I'm still trying to decide whether to carry on or swap.

Re: OMC Stern Drive Stringer Tilt

Badman i see you pulled the motor, how was the coupler and the splines on the ball gear shaft?

Got pics of them ? It's a one piece coupler correct ?

Got pics of the motor, whats up with that ? It running ?

I am also interested in the risers how did they work that?

Re: OMC Stern Drive Stringer Tilt

Sir; no insult to you, but as i asked in the pm may we communicate in the open forum ?

There are better trained minds here and would be to your advantage to have them read the posting between us.

More minds more ideas to help YOU.

And thats what everyone who posts here are interested in achieving, getting the information out, so when someone who needs help can learn, and use the information to the best possible result.

Thank you for your understanding.

Re: OMC Stern Drive Stringer Tilt & engine mounting

Re: OMC Stern Drive Stringer Tilt & engine mounting

Meant to post this one open. Here it is again.

Yes i got the motor out asap because the whole thing was very poorly installed and the stern area and engine bay looked like a bomb had hit it!
Posting some 'Before' pics to the website today.

The previous owner must have given up half way through the engine re-install and i think i know why.. They didn't have any current running to the stern drive gears so when they turned the prop to turn the drive shaft on the stern drive that connects with the engine (ball gear shaft?) the shaft didn't turn and the splines didn't match up and therefore the engine couldn't sit into place and mount the plate properly.

When i found it the engine wa on one mount and half off the other (port). The port side transom plate or stern drive mounting plate had a gap of about an inch!
Basically they took the engine out to rebuild it which they have done. They replaced the head, the valves, the push rods, the rockers, and possibly the rings i don't know.
All i know is i was told by the keeper that it was rebuilt and i have found all the parts they replaced on an old dusty sofa!
This includes all the bits i just mentioned and cam gears also.

Initially i took one look at the manifolds and thought that they were cast iton and ruined.
When i finally got the engine out (swung it out on a double snatch block from the barn roof) and got the manifolds off i was pleased to see that they were in fact steel and cutom made.

Also on of them is fine except for the mounting face where the exhaust passes out which i will fabricate.
The other is not so happy. It is ruined except for the flanges which are fine so i will cut off the existing mess from the flanges, weld on a new exhaust box section to match the existing dimensions, enclose this in a water jacket box section with in and out port, as round as i can make it to match the other (though not too concerned as is just water) and finally mount a new box section to replace the rusted out rear box where the exhaust leaves through the transom.

The engine is also missing a high tension lead and it's starter motor was sitting in water so has had it.
However, When i took the manifolds off i freed the flaking rust from the fly wheel, sprayed the whole engine including carb linkages with oil release spray (great for siezed or gunged parts and everything started to free up.
By the end of the session i was turning the engine over by hand on the fly wheel and had the starter motor installed and was turning it over on the battery.
Until the starter motor gave out (with some interesting popping and shorting sounds!).
Should be easy to replace from the scrap yard.

Next stage is to replace a few pipes and bits on the engine, rewire the coil and starter solenoids and reconnect the fuel lines.

I haven't even started on the fuel lines! There seepossibly more oxidisation between different metals over time?ms to be strange white puffy corrosion around the tank / outlet pipe area.

You mentioned riser. Thats the manifold lower part right?
Also the ball drive gear shaft is fine. It s the first thing i checked.. the splines that is and they are perfect. Quite a lot of grease in there. The male and female splines shafts are both good.

One concern i have is the mounting plate which you can see in the pictures on the website.
Being Ali it has chemically reacted with the steel to corrode in it's own interesting way. There was a copper gasket in between but it wasn't doing much.
Must have been a very fumey boat before the rebuild!
cheers
Badman

A real cute little specimen. The manis looked quite resourseful.

Even the intermediate housing, and I use the term loosely, looks jury rigged. Maybe badman could use that cute little V4 to power a generator or something!:cool:

Never thought the words could cross my lips but I think this boat would be a prime candidate for a nice little 4 cyl Merc setup.:eek:

Re: OMC Stern Drive Stringer Tilt

Ah, but! I've been to England and I have seen what our beloved cousins could accomplish with limited resources. I'll be anxious to see what badman comes up with.

May not be to my standard 'cause I like to do things in a way that does not just make them viable in the short term but ya gotta do what ya gotta do!

Re: OMC Stern Drive Stringer Tilt

You guys ever see junk yard wars on tv.

I swear this is it without the teams.

And i feel for this guy.

I found the links to the pics, not one thing is not fugazyed, jury rigged, or i don't even want to use the other words.

I studied the out drive the best i could, and the steering whats with that ?

I still don't know how they brought the water up to the drive except maybe that pipe on the side.

This tub i swear ain't worth the time or the money to fix.

Stick a outboard on it if you have to use it is all i can think.

Pull the drive and sell it and the motor also.

And plug the hole in the transom.

Sorry to be so blunt but the truth hurts sometimes.

But i don't want to post that it's worth the time or the money.
