Project Lomac

Limey Linda · 05 May 2007, 23:32

I am starting a new thread to record the progress and experience of what is going to be a big project. Hopefull some of my experiences will be of use to others.

Today's work:

1. Pump up tubes and brush with soapy water to find leaks in 2 of the 5 chambers. Found 3 leaks two of which were pin holes and the third porosity in a threadbare area.

2. Been searching for someone that knows about Lomac boats. Called a guy in Aussie land and left a message. George ( NSW) called me back and gave me a whole bunch of tips. WOW. Thank you George.

3. Stripped out the power steering cylinder as the seals are leaking. Have found a local guy that will fix.

4. Removed cracked windshield by drilling out the rivets.

5.Ran a compressed air line out to the boat and tested using a rotary sander on the tubes. Worked great with a foam pad on the disc and 200 grit. Tubes need to slightly deflated to reduce over sanding high spots.

Not enough done worthy of taking photos of.
Regards, T.
PS. My legs ache from climbing in and out of the boat

PPS. Have attached a photo of my best friend Jake

Hey, another project thread, sounds good to me, I will be following this with interest. Project Lomac sounds good, has a military or aerospace ring to it. Post on!
Cod will be around here shortly, anytime a new thread goes up....

From one project boat thread starter to another, I feel privileged to have had the honor of posting the first reply!

Have received black paint for tubes and done a sucessful test. Still waiting for red paint to fix the porous stern chambers which go soft after 2 days. Still cleaning a section of tubes at a time with muriatic acid and xylene; not bad effects yet. Removed bent console rail and straighted; fortunately it is made of heavy chromed brass so not to much of a problem, have re attached to console with wife's help to align holes. steering cylinder goes in for re-build next week.
Fired up the tow vehilce to haul boat out for some photes and noticed a serious tire( tyre) problem. See photo. Removing one of these in 105 degrees F. is a major job. not to mention the cost of a new one.

Well done on the hard work. I'm sure you'll appreciate it when your finished.

I'm surprised your moaning over the cost of the tyre. For the size of them they ain't that expensive in the UK. Only time its a p___er is when its got loads of tread on it and you have to buy a new one.

Keep up the good work and the pictures. Like the mutt, is he your guard dog !

Limey Linda · 13 May 2007, 22:14

Hi Bigs
Those are 16 inch wheels, with 8 studs and cost of tire is approx. $175 inc. fitting and lifetime warranty. Yes, there is a ton of tread left so I am P-ed off. Where we live we do not really need a guard dog but he will make a lot of noise and then lick the burglar to death. Of course the trusty 12 gauge will sort any problem once the noise starts.

Your tyre still seems a litttle expensive at about £90 although I can't find any UK links to show you. My last purchase of a Goodyear in that size was £75 each. I say this as I thought the US would have been a lot cheaper for such things.

Trouble with buying tyres in the UK to get the best deal its a case of phoning up the tyre fitters on a day to day basis to get the best deal.

Anyway best of luck with the boat and hope you get it on the water soon. Then at least you'll feel your money has been well spent. Nothing worse than having a boat thats stuck on dry land.

Have been dealing with same tyre store for 15 years. They fitted a new one for 49 bucks. I am well chuffed. Now we are mobile again.

The hardest part of this little incident is removing and refitting the wheel.
The bl**dy things weigh about 50 pounds and I have a dodgy back.

Decided I should have a service manual for the 200 Mercury. Reviewed all non factory stuff and when they want $30.00 for a manual that covers 3 hp to 200hp I thought that the manual must have to be 2 feet thick if it has any detail. Ended up ordering a factory manual for $75.00. Hope it will be a good investment. Mercury have a good site where you enter serial number and model number to request the correct manual.
Cheers, Tony

Limey Linda · 16 May 2007, 22:07

I have a 200hp Merc but is does not have Merc. controls. I understand there is a buzzer that indicates if the oil injection is working. If I have no buzzer how can I check the injection operation. I just purchased a heavy duty set of muffs so I start the engine at home. Any help would be appreciated.

Tim M · 16 May 2007, 23:46

I think you'll find the buzzer only sounds if your running low on oil. Not sure how to check about the oil injection....that said on the various Mariners/Mercury's I've had I think I'm right in saying that the oil gets "injected" before it goes through the internal filter/separator. If this is the case the fuel in the filter bowl will be slightly blue (or whatever colour your two stroke oil is).

Nos4r2 · 17 May 2007, 00:23

Is there a buzzer on the motor on the 200?

The commander 2000 controls I had on the 4m had the buzzer built into them and no buzzer on the engine.

Limey Linda · 17 May 2007, 01:15

Thanks guys will have to go and look tomorrow. Hope the service manual arrives soon

Mine is on the control end of the engine loom

Limey Linda · 17 May 2007, 19:08

It would appear that the only things connected to the loom are the ign. switch, the tach, tilt switch and tilt gauge. Have managed to find the colour code for Merc wiring ie. what does what. Guess it is going to be head inside console with the old AVO and ring it all out. Just like repairing a leak under the kitchen sink.
According to Mercury, 1 beep when you turn ign. on is a system check, beep beep beep is oil low or not working, and continuous beep is high temp.

fast fred · 20 May 2007, 10:41

merc wires, tan/blu = temp, black/ yel = kill switch, black= ground, gray = tach, red = constant power, yel/red= N safety, purp= key power, yel/red= starter

this should cover the harness, on the trim, green is for grass= down, blue is for sky=up, mite be green with white, and blue with white

Limey Linda · 20 May 2007, 13:10

That is great nfo. Fred. Thanks very much. I have found the warning buzzer; it is wire behing the ingintion switch and is works

Got started early this morning.
1.Removed and clean both in line water separator and Mercury filter/ separator
2. Purchased a set of heavy duty flush muffs and fired up engine for the first time and it idled great.
3. Discovered that the consol felt a bit loose. Found the stainless bolts that secured to deck and tightened. Fixed problem.
4. Installed small 4 amp battey charger under battery hatch to keep it topped of while on driveway.
5. Found inspection hatch to get to fuel tank sender. Tank appears to be stainless

6. Formulated a plan to install second battery.
7. Received E mail telling me that the Tuff coat tube paint is on it's way
8.Will be collecting the overhauled hyd. steering cylinder tomorrow.

Decided I was tired and deserved a beer; but would do one more easy task: remove prop. and lube the splines. Found approx. 20-30 feet of fishing line wrapped around the shaft behind the prop. It had welded itself to the shaft seal. Despite carefull removal half the shaft seal came of with it. Oh bother, now I have to drop the bottem end.

Limey Linda · 20 May 2007, 20:02

I am going to take the boat to the local Merc. dealer anyway for a service. I am considing doing the lower end repair myself, before I take it in. How big a job is it? will include impeller replacement also. Has anyone done it on a 200 Merc? Last time I did this it was on a 50 Merc. 35 years ago

Nos4r2 · 20 May 2007, 22:06

Personally if there's any evidence of salt water corrosion I'd drop the lower unit and take it in to a shop for someone else to do.

Limey Linda · 20 May 2007, 23:51

Thanks for the reply Nos. There is no evidence of any corrosion. Have found an exploded view of the gearcase and it looks as though I can replace the two seals ( inner and outer) by removing the bearing carrier, which is held in with a big arse internally castelated nut which may need soaking in release oil and a made up spanner to remove. Has anyone done this or should I bite the bullet ( wallet) and have the whole gearcase overhauled. Any input from Fred on this one? Have already soaked it down with Break Free ( CLP) just in case I get brave enough to do it myself.
Thank you
T.

According to reseach I have done this is a well known problem caused by fishing line tearing up the outer seal.
