    DP290 service process?

    Hi all, Going to service my own engine this year which is pretty straightforward, but would like to do the drive leg too. There's nothing wrong with it, so just needs the oil change, etc. So far, I think I just need to do the following: - Open up the drain plug at the bottom, take out the...

    Quick question: bulb type for the penta instruments?!

    Hi all, just to save a trip down to the boat, does anyone know off the top of their head the bulb type used in the Penta instrument panels (mine's an AQ205A)? Thanks in advance!

    Uprated carb for penta AQ205?

    Hello all, I've got an AQ205 which is running pretty sweet now after a top end rebuild. I'm thinking I'll maybe stick in a 4-barrel carb to bump up the horsepower a bit. What's a good model to install? Does anyone know of one going second hand? Thanks in advance!

    Speakers with lowest mounting depth?!

    Hi all, I'm replacing the speakers in my boat - the previous models were rusted, and pretty low quality units. The issue is they need to fit into my radar arch which isn't very thick at all. With the reinforcement in there, it leaves only 1 inch of depth. I can perhaps put a spacer on the mount...

    AQ205A Not cranking

    Hello, Just tried starting the engine today which hasn't been used in maybe a month or two, and it's making a not very nice noise when I try to crank it. I figured it was a dud battery, but I brought down a fresh battery as well as used my domestic battery, which is new and well charged. I'm...

    Using isolator to regulate alternator & shore power charge

    Hi all, I'm looking to re-wire my boat as the current system doesn't allow me to crank the engine from the domestic battery without the use of jump leads. I would say my wiring diagram was like Diagram C from the following list: http://4power.tripod.com/id40.html It has two cut-off switches -...

    Engine running makes lots of radio noise

    Hi all, Just popped down the boat to give it a mid-winter check over. I thought we were having issues with the alternator with the voltage looking a little low on the insruments, but it was a bad connection on the instruments. Anyhoo - I was checking the other systems, and I found the VHF had...

    AQ205a alternate alternator?

    Hi all, Just went down the boat and fired up the engine so it's not sat for too long over winter. Looking at the voltage indicators, they stayed static around 12v, and weren't the normal 13/14V when charging. Not good news. Taking a look online, a new alternator is ?250 which is crazy money...

    Clunking noise when engine idles very low (~500RPM)

    Hi all, Our AQ205A blew a cylinder head gasket. We had poor compression in a few of our cylinders, so we rebuilt the top end: skimmed the heads, put in new inlet valves, and had it all ground to fit nicely. We got the engine back together and set the timing up correctly, and the engine was...

    Where can I buy valves for an AQ205a?

    We've got an old AQ205a which needs new inlet valves. Looking at the Volvo parts places, it looks like they're out of production (http://www.marinepartseurope.com/en/volvo-penta-explodedview-7742810-21-15540.aspx). Does anyone know where I can get hold of a set of 6 inlet valves for an engine...

    Newbie question: how do I drain the oil?!

    sounds like a daft question, but how would I go about draining the oil from my Penta AQ205 whilst it still in the boat? naturally, I can't get underneath the engine with a drain tub, and I don't want oil in my bilge for the pump to pump out into the sea! curiously, there's nothing in the...

    AQ205a - upgrade to electronic ignition?

    Hi all, does anyone know where I can source an electronic ignition upgrade kit for a Penta AQ205A in the UK? I'd like to get rid of the old-fashioned distributor & rotor system if possible, and hopefully improve fuel economy, reliability and perhaps performance at the same time. Anything I need...

    Penta AQ205: sealing sea water hoses so I can take the head off whilst floating?

    Long story short: we think the timing was off which has lead to pre-ignition and a plug melting. The core of the spark plug is missing, and now we have zero compression in that cylinder, so we suspect a damaged or broken valve and need to take the head off to see where we go from here. Craning...

    AQ205 timing sensitivity

    Our engine was 2 degrees short in the ignition (6 degrees instead of 8 degrees before TDC at 750rpm). The engine runs fine, but could being just 2 degrees short cause us problems? Many thanks in advance.

    EFI Conversion on a AQ205 Penta?

    Hi all, I've seen some kits (http://www.holley.com/534-183.asp) out there for converting a carb engine to EFI. Has anyone had any experience of this? Will it improve fuel economy significantly? Is the pain worth the gain? Does anyone know of a kit that will work well with a Penta AQ205? Many...

    205 Penta, floods really easily and hard to start

    Hello all! I've got a Penta 205, when you crank it from cold it will kick in every time, but if you stop cranking too soon it'll stall and then is an absolute pig to start. We tried leaving it for a good half hour, then cranking with zero throttle and moving up. It doesn't even splutter. The...
