    Slop in DP290 power steering

    Thanks, it’s a Morse rack and pinion, so I think the whole lot - helm and all need to be swapped out.

    Slop in DP290 power steering

    Thanks both - very much appreciated. It’s a haul-out year, so I’ll throw some money at the steering. Cable and gear unit are probably sensible things to change out at this age as you say. Wouldn’t want it to give out while I’m out at sea. Is the length going to be marked on the cable, or is it...

    Slop in DP290 power steering

    Hi all, When I steer I feel a notchy feeling as I change direction. Looking at the power steering actuator, there's a little movement where the cable goes in that could cause that feeling. Is that normal, or is there a fix? Video of the piece moving here: slop Thanks in advance!

    Trim motor for old DP290

    Hi all, The tilt and trim motor seems to be jamming on my 1989 DP290 drive. The relays click, and I get +12 and -12V at the pins that feed the motor when I operate the switch, so it looks to be the motor that is shot. I see it's Penta part number 3587106, but found OEM penta parts to be...

    Holley carb - accelerator pump adjustment

    For future people - this was a jammed check valve. I’d rebuilt the carb, but not taken the pump shot shooter apart as it had been fine. It was dry and stuck, so penetrating oil and a wiggle with a small flathead as I blasted the hole in the carb body with air and it came out. A quick clean and...

    Holley carb - accelerator pump adjustment

    Hi all, I'm trying to get the accelerator pump set correctly on my carb, but something seems off. With the carb closed, I set the pump lever to just be touching the adjustment screw base - I can get a piece of paper in there, so can't get any more loose. However, at WOT, the spring is pushed...

    MSD 6m-3l worth it?

    Hi all, I have a 4.3 v6 vortec which has a delco est ignition. Would there be any tangible benefits to moving to an MSD ignition? From what I’ve read, they don’t seem to alter timing much other than setting low advance for easy starting, so doesn’t look like there’s be much in power gains, but...

    Garmin GMI10 NMEA connectivity

    Thanks guys. I’d not connected the green and white cables as I thought they were CanNET. They were the earth connections for nmea0183.

    Garmin GMI10 NMEA connectivity

    Hi all, I have a Garmin GMI10 that I'm trying to send GPS data to using nmea 0183. I have other devices able to receive GPS coordinates from the same charter plotter, so I'm sure that is configured correctly and sending the correct sentences. So, Garmin recommended the following cable...

    Understanding how engine died - water on inlet and exhaust sides

    so in thinking about it, my current theory is since there was so much water inside the engine, the breathers were throwing out loads of steam/fumes, and the breathers are connected to the flame arrestor, so when the engine shut down, that moisture would have sat on the inlet side and on the...

    Understanding how engine died - water on inlet and exhaust sides

    Hi all, this story goes back a couple years now. I'll try to compress the background as much as possible. Engine is a 4.3L V6 vortec. Raw water cooled. - had leaky inlet manifold (vacuum leak, not water). Had manual provided by engine supplier for non-vortec model and over-torqued inlet...

    New heads after water ingress, but lots of smoke from rocker cover breathers.

    Hi all, So, I have a 4.3 v6 vortec. We had (salt!) water ingress from a leaky inlet manifold. Unfortunately it took a while to get the engine out, and the mechanics found some of the valve seats were shot from corrosion. So, we replaced the heads, the engineer removed the sump to clean it, then...

    Rocker cover breather in a 4.3 V6

    Hi all, Long story short, I had to re-fit my inlet manifold as I had a vacuum leak in between the inlet manifold and top of the engine block. I used new gaskets, sealed it, torqued up etc. by the book. As part of it, I rebuilt the carb, using a lighter spring for the secondaries which are...

    Wiring colours for Garmin Fishfinder 400C transducer cable?

    Hi all, Long story short, I cut the connector on my airmar B60 transducer that connected to my Garmin 400C as I was replacing the Garmin with a Raymarine. However, that didn't work out, and now I need to revert, and of course the original connector has gone missing. So, I have a decent splicing...

    Penta steering actuator: fair amount of slop

    Hi all, Apologies, third steering post from me! I'm going over the whole system in detail this week. So, the actuator is a Penta 852741. No leaks on it, but where the steering cable goes in, I'm seeing a fair amount of slop. I get nearly a quarter turn of the steering at the helm before there...

    Steering - can it jam the pump?

    Hi all, You might have seen the thread where I'm looking for mounting bolts for my saginaw pump. I'm putting the sheared bolt down to metal fatigue, as it must be around 25 years old. However, two years ago, I had another issue with the power steering with the pulley being badly damaged, and...

    double ended studs for saginaw pump in UK?

    Hi all, I've had one of the double-ended studs shear on my saginaw power steering pump. Looks like they're hard to find in the UK, and it's going to cost $46 to deliver from the US! Does anyone know where I can get them, or something I can use instead? I think it's a 3/8-16 thread. I could just...

    Going B5 to C4, but heard C4 is less coarse pitch?

    Hi all, Quick background: My boat used to have a penta AQ205 with two barrel carb. I re-engined with a vortec 4-bbl, pushing around 220HP. Drive leg has always been a DP290 with B5 props. With the new engine, it tops out at 37kts at WOT, and I think it hits 4800RPM, if I can believe my...

    DP290 retro fit anode for stainless props or hand anodes from props?

    Hi all, I've managed to source some stainless props for my DP290. However, I hear they burn through anodes much faster than aluminimum props do (I'm in salt water in a permanent wet mooring and need to use zinc anodes). I've heard of a couple of solutions: 1) retro fitting an extra anode to...

    Raymarine E7D flickering screen - workshop/rebuild guide?

    Hi all, my E7D has a badly flickering screen. I've seen a few posts about cleaning contacts, etc to get it working again, so was going to take it apart to have a look around. Raymarine want £300 + VAT to fix it which is pretty extortionate for an older unit like this. Any workshop manuals or...
