    Install additional fuel vent hose into existing line?

    Hi, Been having a problem with my fuel vent line, looks like quite a bit of fuel gets into it which makes filling up a slow process. It doesn't seem to affect engine performance as I guess it sucks it into the tank at that point and gets good vent flow. The vent is currently part of the filler...

    Bravo 3 water pickup hose and engine run

    Hi all, My Bravo 3 is currently being serviced but in the meantime I want to change the engine oil. Can I run the garden hose straight to the water pickup tube on the left and then run the engine to warm it up and winterise? Thanks

    Mercruiser 3.0 Rough idle then stall after use

    Hi all, I have a Mercruiser 3.0L 2005 with TKS Carb. Boat has been running well and been out for several trips this month. Yesterday after about 2 hours of use it suddenly developed a rough idle. Normal idle is around 700/800rpm, but now it jumps between 500 - 1000 before stalling out. I...

    Worth putting in new bearings or buy a new hub?

    What do you guys think? How would I even start getting through to the actual bearings or should I just get a new hub? This trailer goes in salt water a lot, not sure when the bearings were last done either.

    Power Steering pump - bolt at bracket?

    Hi all, I'm missing a bolt at the front of my power steering pump to the bracket. I don't have access to the boat at the moment, so I wondered if anyone knows if I can get the bolt in without removing the pulley? On the marine engine website, here...

    Mercruiser 3.0L Carb confusion

    Hi all, My engine, 3.0L 181 Mercruiser TKS Carb (0W601238) started to die on me in idle a few ago, to the point that I was convinced that the idle assembly of the carb was blocked. The most repeatable problem I had was: start engine from cold, starts fine, runs fin, until the engine warms up...

    Shifting into forward needs adjustment

    Hi, I have an Alpha 1 Gen 2 outdrive, with the shift assist on the shift plate on the engine. (3.0L Mercruiser) When I shift into reverse gear, it is pretty much instant with a dull clunk as the gear engages, all good. When I go into forward gear however there is a lot of clunking, like...

    Paint ski locker lid

    Hi All, I've recently cut and polyester resined my ski locker lid (made from ply) and now I'm planning to paint it. Originally I was going to give it a good wash and then a light sand before painting, but I've read somewhere (I can only assume here) that you can mix a bit of paint in with the...

    How low into the bilge should blower tube go?

    Hi all, I read in a lot of places that the blower tube should go as low as possible into the bilge. I have a Maxum 1700 with 3.0L Mercruiser. The blower tube effectively stops where the starter motor is, rather than going down under the engine, is that ok? Thanks

    Mercruiser 3.0L start on stand - wiring

    Hi all, Read and asked a couple of questions about running an engine on a stand. All set to go except for the wire running to the coil. A few guys hook up a 12V connection and then disconnect it to stop the engine. My coil is different from most of the videos I've seen, so how would I got...

    New ski locker hatch - wood

    I'm making a new ski locker lid/hatch for my Maxum. Currently the interior is carpeted, but next winter I'm thinking to remove all the carpet and check the deck (probably replace, lets face it), then gel coat it instead. For the ski locker what I would like to try is a piece of either...

    MerCarb torque stud nuts

    Hi all, How on earth do you torque the carb stud nuts to the manifold? I can get one quite easily with the torque wrench, but the rest are tucked right in the corners which makes putting a socket over it quite difficult. What tool am I missing that would probably solve the problem in a few...

    Mercruiser ground stud, replace with ordinary bolt?

    The ground stud on my flywheel housing got pretty badly corroded and I eventually broke it off. Does it have to be replaced with a specific Mercruiser "special ground stud" or would any bolt do? As long as I got a stainless steel bolt with some nuts and metal washers I'm not sure what would be...

    How to run the engine when it's not in the boat?

    Hi all, I have a 2005 Mercruiser 3.0L TKS that I have been cleaning up. I would like to run it before I put it back in the boat, and seen quite a few videos. There doesn't seem to be a to do / to check before doing it. Any advice? Required is obviously water, battery and fuel, and I've heard...

    Carb Gasket(s) question

    Hi, I received two gaskets for the carb when I ordered a new manifold. Am I meant to be using both of them? The old gasket is compressed and broken so I'm not sure what was there before. I've attached a picture showing the 2 new ones. I have a 2005 Mercruiser 3.0L serial: 0W601238...

    Starter motor shorted?

    Evening all, I have a 2005 Mercruiser 3.0L, with what I believe to be a PG260F1 starter motor. I'm working on the starter motor at the moment as the solenoid on the motor was not engaging. I got that working, but now that I have put the starter back together I cannot get the starter motor to...

    Hi all, Any body care to have a guess as what this liquid type stuff is? The photo shows the exhaust port of cylinder 4. (Mercruiser 3.0L 2005) The engine has been out the boat for about 2 months now, but I only recently got the manifold off. Thanks in advance!

    Hi, I've got a 2005 mercruiser 3.0L that I am currently stripping down to repair / replace various bits. It's been used for a season and the compression numbers have all been ok'ed. So the question is, what do I do about these rusted nuts/bolts holding the head to the block? The advise at...
