View Full Version : Finally got to splash the b!tch tonight

After two years of wrenching/screaming I fiinally splashed the Cig toight, only had time for about an hour of running.

Good part is, with all the weight shed from using aluminum parts it actually sounds like a powerboat instead of the gurgling, sputtering, boat is drowning from tips being just under the waterline sound. The boat planes off right at 2k which was unheard of before. I ran it for about half an hour at idle in gear with half an hour of 2 to 3k RPM inbetween.

Some points to ponder: Running on the hose I had what I thought was reversion isssues in one motor. After pulling the SM full length risers off tonight it was clearly condesation and only showing on the top half of the elbow on one side and the top half of the elbow extending down the top half of the riser about half the overall length on the other side. The rest of both pipes and both manifolds were dry as a bone. On the SBC manifolds the supplied rubber jumper hoses seem to be a tad bit kinked at the bend. Could this be the culprit of over/ under pressure at the point of entry into the riser jacket?

Seccondly, The "drilled" 160 degree Hardin T stats never made above 140 degrees on either motor "verified by IR thermometer". Could this be becase of the holes drilled?

Last, The 212 degree Hardin oil T stats never made oil temp above 200 degrees "again verified by an IR gun" Oil temp dropped down to about 150 once back at idle in gear. Cold oil pressure at startup is roughly 60psi per side, after 15 min at 3k rpm it dropped to about 25psi at idle and rose to 35-40 after running back at idle for a minute or two.

Somewhere between the block adapter output and the oil T stat input leaks like a sieve on both motors at temp, I knew this before from running on the hose, most likely an AN to AN seal problem.

Congrats Tony. Looks great. My guess would be the drilled stats. How many wholes?

Congrats on getting her back in the water!!
Motors look great.
You had to expect a few little gremlins to iron out.
Had to feel great running her again.

The water temp can vary greatly depending on where your sensors are. I wouldn't worry about that until you are running more cruise and WOT tests. Just make sure your oil temps are warm when hitting it.

On the AN fittings. Chris knows more about those than anyone else on the board. PM him. Sounds like the high pressure/low pressure fitting match-up issue, but he should know more.

I'm assuming your sentence about oil temps and pressures was a liitle mixed up because you were excited. Temps rose up to 135 to 140 and pressure stayed at 25 PSI at idle after the engine was warm?

By the way, what is the lake water temp with the IR?

I would be a whole lot more if it wasnt for theese god dammned oil leaks. At 200 degrees its all but a steady stream coming off the bottom of the T-stats.:ack2:

Congrats! First time out is a little nerve racking isn't it. I know first time I got mine on plane after all of the glass work, engine, etc. etc. I was nervous wreck.

Wow, that clear engine hatch is so CLEAR, its invisible :)

On your oil leaks, are you sure you have AN to AN and not AN to SAE fittings in the T stat blocks?

Yup, Russell fittings on the T stats and Aeroquip on everything else. Heres the kicker, the Aeroquip hose ends to Russel fittings on the T stat ports dont leak. The leak has to be comming from either the upper cone of the T stat itself, or the M Aeroquip to M Russell fitting that is connected by an Aeroquip double female coupler. Both motors are leaking in the exact same place.

Can you isolate the connector M to M by wrapping it in a small taped on rag or something to isolate the leak location?

Tony

Might have to try that, this business of stripping the exhaust completely off to get to theese things is starting to get old. One other thing Im wondering, with 212 degree T stats why did my oil never make it past 200 degrees? And why did it cool back down to 150 at idle? Toil temp sender is bushed into the oil pan drain plug hole.

Mine act similar. You're measuring the temp away from the thermostat. The thermostat opens and closes based on what it sees, not what the temp sensor sees. 200 is a decent temp, 150 is a little cool, but I bet it's also a misread because of location. The thermostat is reading temp on the way into the cooler. My guess, your pickup is reading temp after the cooler before full engine circulation.

The worse oil leak I ever had was behind the adapters to go to external oil filters. Took forever to get it right. Gen 7 blocks.....

Congrats Tony. Don't worry about the temps unless you get condensation in the oil. Merc put 140 thermostats in all of their old carb engines. 200 is also fine for oil temp at cruise.

Tony
08-18-2009, 12:08 PM
I installed the T stats so I wouldnt have to even consider condensation. They are plumbed exatly per the diagrams that came with them and so far dont appear to be working.

Yea, that's enough to p... you off. Take them off and send them back for a refund. Actually, I'm not using mine anymore either.

I have been told that either -8 or -10 JIC/AN will thread into the 45 degree SAE fittings. You may want to confirm. Other than that, nicks or burs on the faces make the fittings useless. If they're o-ring swivels, replace them. I've never trusted them- at least not the aluminum hiotrod stuff. If you need them, get the all-stainless Aeroquip one's. When you see the price, you'll probably find a way to live without them.

You shouldn't have any issue getting the temps up there, but you're going to have to have the engines spinning fairly hard to get the oil temp up. If they're plumbed correctly and functioning properly, the t-stats divert oil from the cooler until the temp rises. With no cooler, the temp should come up pretty quickly.

Regardless of having an oil thermostat system in place, if the engine isn't making combustion temperature the oil temp will cool down lower than 200 degrees. The systems that bypass the oil cooler rather than the water tend to keep the oil warmer but even then if you're just idling for a while you wont make that much temp.

Tell me about it! My buddy was looking to purchase some -12 from Mc Master and they wanted something like $50 a fitting.

About your oil leak, -8 SAE (45 degree) and -8 JIC (37 degree) are the same diameter and thread pitch. It's normal practice to use combinations of these fittings together on lower pressure applications such as engine oil. I think the difference in degree may help seal, however you lose surface area so watch out for nicks. Since both engines have the same problem I would look to see if one of the nuts on a female fitting was bottoming on the threads or body of the male fitting and not allowing the seat to contact. Not all brands of fittings are compatible. You could check this by trying to rotate the hose after the fitting is tightened, you shouldn't be able to.
Really nice looking 28 I'd like to see more of it. Years ago I almost bought one myself, had TRS' and 300 Tempest's. Good luck.

Sector, welcome to Serious, being from Batavia, you gotta know Birdog. Theres a few more pics of what Ive done to the pig here: http://www.seriousoffshore.com/forums/showthread.php?t=5779




Back to theese oil T stats, does anybody here know the exact design of the Hardin units? I vaguely remember looking inside the ports months ago before I installed them and wondering just how in the heck it sealed off the oil flow to the cooler. Do theese things actually block 100% of oil flow to the cooler until desired temp is reached, or just some of it? And route 100% of oil through the cooler after the oil temp rises above 212?

Yes. They are just a thermostat that has an open/close temp. When I plumbed mine, I was also told it didn't matter which way the oil flowed because of the open/close only position.

Call them and see what they say. They've always been extremely helpful to me.

I've not had a chance to meet Birdog but I have seen him a few times on the river in both his Top Gun and when he had his Bullet.
I looked at what you've done to your 28 and it really loooks great. The one I looked at a long time ago was in Florida and was just like yours but had brown trim and I think a taller windshield. I loved it but my wife didn't. Settled for a 260 Stinger at the time which was nice but no Cig.
