How high is the water relative to the Y pipe?
Was the exhaust bellows recently removed or was it always like that? I think you should re-install it, remove that exhaust tube because it leaves the exhaust passage wide open to water rushing in, or put a flapper over that opening instead.
the connections for the fuel pump look a little sketchy, might want to go over them & make sure they are clean and tight.
I had a problem with a sticky anti siphon valve on my boat years ago, I was not familiar with marine fuel systems then, my mechanics caught it and the boat has run fine ever...
well when the plastic screen was covered with them that's what I had to do, had to come up with a way of using 3 scissor jacks to get it apart, then cleaned it all out and painted it INSIDE too!
Why I'm getting an outboard next time! Amongst other reasons....
I used two bolts on the front drive...
You could try the spray wand but mine has just 4 big holes so I just spray it pointing down, up and straight thru. And I only get a couple after a season in salt (5-6 months). After spraying make sure the holes are open, I doubt that the paint will clog them because the spray on Trilux is very thin.
If you read through Load Rite's documentation on hot dip galvanizing you can see that it does galvanize the inside of the box section as well and from everywhere I can see the inside of the frame on my old '94 is galvanized, or else I would probably not have had it this long!
But I have seen...
You can remove the thermostat housing and the front circulating pump and look inside the intake manifold and the block, you can't see much but it will give you an idea how much corrosion there is inside. If all you saw was light surface corrosion that's one thing but flaking rust, will continue...
100% you must spray in there or else you'll have barnacles if you are leaving the boat in salt water. In fact my OMC Cobra had a plastic water screen in there that I had to remove because I had a chronic problem even when painting it, with barnacles clogging the water inlet. Much better since I...
If you’ve got a whining fuel pump be sure to check the anti siphon valve on the gas tank. They can corrode and/or get clogged with debris from the tank. There is also a screen on the fuel tank pick up tube that can get clogged. These are fairly common problems that can cause whining & premature...
Ok on this engine the cooling water is pumped up from the water intakes thru the pivot mount then it gets pumped thru the transom mount. Next it flows thru the P/S cooler on the back of the engine then flows forward to the thermostat housing. The cool water initially flows out the exhaust...
I flush out the box section of my galvanized Load Rite every time it goes in the water and it’s held up well. The frame is a 1994 that’s been upgraded few times (longer tongue, longer roller bars, 6,000 lb axle, 5 leaf springs and 12” brakes)….
I think some is intended for pvc pipe & plumbing and does not have corrosion inhibitors. Glycol itself is corrosive so it needs corrosion inhibitors if used in cast iron or aluminum engines. This is why I like using the Sierra PG antifreeze it’s good enough to be used as an engine coolant not...
I bought a lot of used freshwater Cobra spares on eBay and for the most part the parts were in good shape given the age of these parts and the fact that this stuff is just not available new. I have a brand new looking Y pipe, steering actuator, trim pump, spare outdrive and transom mount. Plus...
common in salt water land. Bust em up with a pick and blast out with water hose or compressed air, I would not want to suck them up into the impeller. I spray that area with Trilux II in the spring and paint the drive with 2 coats of the stuff...
that's why I posted the second book, it goes through all that, how points saturate the coil to step up the voltage and how point gap and dwell interact with that...
let's all really learn instead of waiting for sound bytes without understanding theory...
Stone age technology that still works...
The other reason why in this case I'm advising self-teaching is this:
you have an OMC drive system on your boat. OMC went out of business 20 years ago and very few shops will work on these. Its not like a Mercrusier where there is a mechanic in every town that has boating resources, you have to...
All the knowledge I have came from 50 years of self teaching it started with basics you get from manuals then if you can’t get your question answered from the manual then we used to ask real mechanics now you can ask on the net but the net has a lot of mis-information. I don’t mean to be harsh...
You might consider getting a shop manual and learning All the basics as I spent the last 50 years doing myself! This never ceases to amaze me. The internet is not a shop manual!
If you really intend to get this thing running well enough to actually use it’s time to get serious and learn the...
