Hi guys, I hope you can help me out. I recently bought a boat with a volvo penta inboard engine. The boat was overheating so I suspected the manifold was leaking and when I took it off, it was like a T-Bag leaking coolant into the exhaust.
I contacted my volvo dealer who suspects my engine is an AQ115 (although the manifold in his diagram looks slightly different to mine). Problem is a replacement manifold is going to cost me the guts of £750 inc vat, that's more than the engine is worth, so this is my dilema.
Do I:
1. Scrap the engine and buy something else? if so, what do I go for? My boat has a 100 series out-drive and whereas this is old, it does the job. So are there any other engines that bolt direct to the old 100 series, or should I look at replacing that as well.
2. Bite the bullet and buy the replacement manifold... only for something else to go wrong with the engine
3. Is it possible to get the manifold reconditioned? i've heard about ceramic plating, is this a worthwhile exercise
4. Go back to the dealer who sold me the boat and.... pay him a serious visit!!!
Any advice/comments/general banter welcome

Why is the manifold leaking? Has it rusted through? Given the pounds sterling sign I gather you are using this engine somewhere on the coast of England, so I would further assume this engine has seen a lot of salt water. If the manifold is damaged due to salt water not being properly cleaned out there may be many more horrors elsewhere. Chances are the fellow who sold you the engine may not have known there was a problem. You have the engine checked thoroughly to find out how many more problems there are. If its a hopeless case, due to salt water problems, it should go the recycler. Caveat emptor. |

Hi Foxman, you are spot on. The manifold has a couple of pin sizes holes in it which causes it to leak when heated up. My big problem is the rest of the engine was running fine, no obvious adverse effects though it's hard to tell what state the engine is in without running it.
Are there any obvious places to look when checking out the engine (without stripping it down to the crank) or is a total strip down and rebuild the only answer. |

If the rest of the engine is running fine you may be ok. If there is a problem with water leakage in the engine itself there will be water in the oil, The engine oil will turn a milky white. As long as the oil is dark (dirty black to single malt scotch colour fresh out the bottle)it should be ok. Therfore check the oil. I would also suggest a compression check, it should be 120-145 psi on each cylinder (that's a rule of thumb you should check the manual recommended specs)Any lower than 120 and trouble is coming. If both these things are ok I would say it's worth a repair. Given your location, I don't see much benefit in used parts as they probably all have the same problem. |

Have you tried to look for a manifold in Sweden ? If the price could be lower there.
