Yep. Plenty of scratches on my back from that mfer lol

So lets see a pic of the clean oil cooler. What did you do to clean it?

I would trade places with any of you Fountain guys when it comes to bilge clearance. That b!tch I work on leaves me laying across the top of the carburetor if I have to do seawater pump service. The only way I have that kind of room in front of mine is if I take the side panels off the cockpit and slide the rear seat forward about 3 feet. In fact, I have installed wing nuts on the side panels so this is an easy operation. Tired of standing on my head!
Glad you found your problem. How refreshing when it turns out to be something simple and inexpensive - a rarity in the HP boating world. |

35 Fountain with bravo's should have plenty of room in the bilge for strainers. Here is a picture of a 35 with Speedmaster drives, and transmissions, which move the engines forward about a foot. Still plenty of room.

I'm wondering what the water pressure is going to be now...Its amazing it was at 17lbs with a clogged cooler... |
Looks great
|
Probably back to what the factory test sheet says.
|
I'll post my readings and results this weekend. Water dumps may have to be hooked up again. Not to concerned about the oil temp, I'm sure its going to be down but I am concerned about the water pressure. Fix one problem create another, Welcome to boating.LOL
|
can tell you this been helping a friend with a 35 also, 535SC's kept burning 1 exhaust hose, coolers looked like yours, and it had factory strainers as well, did cure the problem, good luck on yours

So how do you burn off moisture..Water boils @ 212 F. seems way too cool for me. So if your running 170 ish and 190 ish you must have some white sludge somewhere maybe under the valve covers. An engine trying to generate heat with no oil or water thermostats will condensate.
There are professional Marine engine builders who have recommended running cooler temps then some OSO members think you need to "burn off condensation" Edit: I'm way behind on this thread! Lol Lots of good posts on here though |
I agree excursion, and I can provide the numbers to back it up tomorrow.

I RARELY have issues with any condensation normally if at all it's in very beginning of the season... April-early MAy

I hear what your saying but from personal expierence not all engines condensate. I agree it's something to consider though.

If it took 212F for water to evaporate, we'd have no clouds.
edit in: but again, I agree, the hotter the oil temp the faster the water will evaporate and somewhere 212F or higher will turn into steam and more quickly remove itself if it's let out of the system (breathers/PCV) |

[ATTACH=CONFIG]544161[/ATTACH]The oil temp sensor is located on the remote oil filter. I believe that is before the cooler. Looking at the arrow on the remote oil filter housing, that oil line comes from the block, feeds the filter then heads toward the oil cooler then out of the cooler and back to the block. I am more concerned about the cruising 3400-3600 rpm oil temps more than WOT. I do more cruising than wot and if i run at wot its not for very long. After the last wot run I really didn't look at the temp, I was more concerned what was in front of me but i can say after stopping and idling for a few minutes the gauge was down around 200-210. No alarms or buzzers. I'll have to take note of the oil temps the next time i open her up.

How about a larger oil cooler. 240 degrees at constant cruise, is too hot in my opinion.
What temperature water thermostat are you using? |

you likely wont see much more that a 20 degree jump from there if he's at 3500 to 4k rpm... its loaded for bear at that point...

We seem to be getting off the subject here..Back to oil temps...I made custom fittings between the exhaust manifolds and the risers allowing me to dump some water overboard thru 2 fittings on each side of the boat. The hose size was 3/8". When that setup was connected my oil temp was 20 degrees less and my water pressure was 5-6 lbs less. reason being, the relief of water pressure allows the water to go thru the cooler faster removing more heat BUT...repeat...My Stainless risers are running a bit warmer at idle due to the reduction of water going thru them...so my question is. Is it ok for the SS risers to run warm at idle??...If so i will re-install the dump lines

why not install a 10 PSI check valve on those dumps so water will cool when idling around and dump when you're beating on it!!

I just wanted to say thanks to all for the help on my oil temp issue. After Running last weekend i decided to remove the end caps on my coolers. I was shocked at my findings. I can't believe the oil wasn't showing hotter and the engine water temp was at normal 152. SAND<PEBBLES>SEAWEED CLOGGED IN BOTH COOLERS.
Curious about the oil temps after cleaning [ATTACH=CONFIG]544596[/ATTACH][ATTACH=CONFIG]544597[/ATTACH][ATTACH=CONFIG]544598[/ATTACH] |
Recently I switched out my 13 plate bellhousing coolers to 8 plate to help build oil temp.
The evaporation on MY motors was not fast enough below 212* . It still takes 5 minutes + around 4500rpm to get the oil temp above 212* in Lake Michigan but at least I can get there now. Ultimately, I`ve learned that the water temp is a large factor in condensation. I can run around warmer Lake Erie or ROTO at 180* oil temps all day without any condensation. Unfortunately building water temp in my motors is next to impossible. Cold water and 180* oil temps on my set up equals: http://33outlaw.zenfolio.com/img/s7/...62154478-3.jpg |

Sounds like a great idea anyway. Who makes a water relief like this at a low psi
however... if you want to run them, take a close look at the STBD engine, you'll see the unit in the chiller right beside the idler pulley to the left of the blower belt... |

Teague Marine has adjustable units... I use them on my superchillers [ATTACH=CONFIG]544650[/ATTACH] not sure if you can blow these up on your computer.. but they are the brass units that are screwed into the front side dump of the chillers... these work awesome and I'm sure they would help you if overall system pressure is a concern for you... 15-16psi wouldn't bother me, IMO

You don't have to boil water (ie: to turn it it turn to steam) to remove itself from oil, or other things for that matter. Evaporation can happen at much lower temps. However, yeh, the hotter it is, the faster it will. |

I agree BUT how long do you want that condensation to stay inside. It will begin to rust parts like valve springs, push rods, etc. Look at the post in this thread on page 11 from ICDEDPPL.
Again, I'm, just stating info against the common misconception that oil has to be 212F or over to remove water. That is all. Hard to type vs speak and convey the message. |

seeing how we are shifting a bit here, I have been experimenting with breather setups on my procharger setup, found what works well for me, run 5/8 hoses out of each valve cover to individual puke tanks, vented to procharger inlet bell. What I noticed was all the water being caught in the tanks, and no oil...just info..

Add a baffle in there and you'll see even more fall out. I work in the natural gas industry, this stuff is my bread and butter. :) |

[ATTACH=CONFIG]544686[/ATTACH]I also have a puke tank on each engine with 2 hoses going to each tank. When i drain my starboard engine only a bit of water comes out. Nothing out of the other engine. Keeps the valve covers cleaner

So what you're seeing there is the vapor is swept from the valve covers at some velocity through the hoses and the speed keeps the water in vapor phase. Then the water suddenly slows as it reaches the puke tank, vapor condenses into droplets and falls out.

That`s interesting. I modifier my oil fills and ran the lines to the flame arrestor hoping to 'pull' some air out of there but I`m not sure how much if any vacuum I get.
http://33outlaw.zenfolio.com/img/s10...81746362-3.jpg If I could pull some vacuum out of this .... http://33outlaw.zenfolio.com/img/s6/...31972071-3.jpg |
You are not really gonna pull much vacuum from flame arrestor. You would need PCV valves hooked to direct vacuum for that.
|
I was told by Nickerson Performance never hook up a pcv valve to a marine motor unless you want to blow it up. Actually when i first got my boat there was one in each valve cover and a hose connecting to a vacuum port underneath each carb. I did remove them when Nickerson built me carbs and flowed them to my engine specs. I really don't understand why a pcv valve would do harm to a marine engine unless pulling unburned fumes and moisture back into the intake to get re-burned could lean out the mixture.

Oil in the combustion chamber can cause detonation.
That said, Hp500 and other motors use an actual PCV valve, not just an open vent off valve covers routed to flame arrestor. |
That's one of those blanket statements that are meaningless - and not supported by reality (Merc uses them, every heavy duty truck, etc). Could you blow up an engine from drawing oil in the cylinders? Yes if you stuck the valve in a valve cover with no baffle. If done correctly, the amount of oil drawn in will be insignificant. The valve covers used on most of merc engines are GM parts already setup with baffles in them for PCV.
I modified my engine to use a PCV - same part and arrangement as HP500s. Properly setup, it doesn't lose much oil to the intake. I set it up to eliminate the oil/engine smell after a hard run, a bonus is the occasional condensation is gone, and so is the water in the oil analysis. |
2nd Update
With the water dumps closed off Water pressure 14-17lbs oil temps 220-225 @ 3200 rpms.Port engine Starboard engine same water pressure oil temps 215-220@ 3200 rpms.. and will the water dumps open 11-14lbs water pressure 215-220 @ 3200 rpms. port..Starboard 210-215 WOT 2 minutes oil temp got no higher than 230 Readings are before the cooler in oil filter housing. So the oil temps got a little better not as much as I expected especially after seeing those coolers so clogged. The water dumps definitely helped. As the water temp in the river cools off I'm sure they will drop more
Thanks again for all the help |
I agree that could be it, but I chased a similar problem for two summers. Here are what I discovered....
1) my guage (Gaffrig) was mismatched with the sending unit. Apparently different ohms which caused the temp to read 2x actual. One problem is never enough, so... 2) suspected bad oil thermostat. One attempt to fix, I pulled the thermostat to force it to flow through the cooler all the time. No fix. Later, we took apart the thermostat/mount housing and figured out the thermostat behaved the OPPOSITE of a water thermostat, so removing it meant never running through the cooler! Turned out to be s bad thermostat and now all is good. |
