Hi all I’m going to be changing the pressure sensor on my VP D4-260. Q: Do I need to drain down the oil in order to change the sensor or just be quick with the change to minimise any loss?

Hi all - I’m going to be doing a leg service (oil change / anodes etc) on my DPH-A sterndrive leg. Q: Can anyone remind me the Torx bit size required to remove the plastic cowl? I recall my bits sitting on the boat are now corroded so I’m going to order some new ones, but I can’t recall...

Hi All - my Max Power Bow thruster is working intermittently on one side. It will work once every 4 or 5 attempts to invoke thrust on starboard - port works fine. I wondering if anyone else has come across the same issue and whether it’s a case of stripping/cleaning the contacts in the...

I previously posted that my turbo was sticking and I managed to free it a bit. I plan on taking a power drill/screwdriver and continue to spin the turbo to further loose any corrosion jamming it. Q: can I simply use the hex head (shown with blue arrow below) on the exposed turbo shaft to turn...

Hi all I wonder if anyone can help with this….I had my boat with single VP D4-260 out for a shakedown run and I couldn’t get to WOT. It spools up to 2,200 a 2,400 with a whining noise coming from (I assume) the turbo. The pressure gets up to 100kpa max. Interestingly I had had the same issue...

Hi I’m refitting my exhaust hose coupling between the exhaust elbow and the transom exit pipe on my VP D4-260. Q: How tight should the exhaust clamps be? They are sizeable clamps (not jubilee) and I want them tight but not too tight that they (possibly) damage the elbow and/or exhaust transom...

Hi all My VP DPH leg showed signs of water in the oil, but a pressure/vacuum test showed no leak! Now I had lost a hub on one of the duo props and the props were grinding together. Is it possible that the water in the oil was due to a transient issue caused by the hub failure, and once the...

I’ve been changing the transmission oil in the leg on a DPH leg and the oil has drained slightly milky. There was no obvious water layer and the full volume of oil has drained. On my last trip I lost the hub on the rear prop which caused the two duoprops to grind together. I’m guessing I may...

Hi, I’m going to replace my (failed) Rudder Position Indicator cable on my VP DPH drive. can anyone advise the best way to do this - should I push the new cable from the inside to the outside or vice - versa?

Hi all - I’m fitting some new props on my VP DPH drive and I’m planning on using some Threadlock on the Prop Shaft Nuts. Q. Can I use big standard blue Threadlock (I’ve some Granville Threadlock) or do I need a stronger / different formula?

Hi all I need to get a new prop set for my VP D4 with a DPH-A drive. I plan on replacing the old Nibral, G series props with the new Stainless Steel H series props. I understand the props have a slightly different fitment and the rear cone needs to be changed. Q. Has anyone else moved from G...

Hi all My engine mounts for my Volvo Penta D4-260 are looking a bit rusty where they meet the stringer. I may have to change them at some point. The question is whether I can change the mounts in-situ without a lift out, taking the leg off and lifting the engine up? The boat is a Jeanneau...

Hi all. I’ve just done an oil change on my Volvo Penta DPH drive and note that there is a bit of corrosion around the oil drain plug, particularly at the lower part of the drain point. See pic… I fitted a new oil seal washer (as advised) and put the leg back together and relaunched. I’m now...

I need to change the Bellows on my Volvo Penta DPH sterndrive (with a D4 engine) and have asked for a couple of quotes to do the work. Can anyone advise what sort of figure I’d be looking for that work? It would be to remove the leg, supply and fit the 2 bellows and the 1 water hose. The boat...

My domestic bank has finally thrown in the towel; not bad considering the batteries are at least 8 years old. So I need to get my hands on a couple of 110Ah batteries for the domestic bank (and I’ll probably swap the engine and thruster batteries soon also, although they are still performing...

Hi all I’m planning my escape for a future retirement and while I have a nice 30ft’er in Scotland I’m wondering if I could live the jetset lifestyle, for at least a year or so, and then go back to normal life. Do you think it would be feasible to buy say a used 40ft’er in the Med for 12...

How much of a rumble / vibration should I get from a Volvo D4? Should it be super-smooth at 3000rpm or should I expect a bit of vibration felt at the helm / stern area?

Hi all, can anyone advise me the dimensions for a Volvo DPH drive? I’m trying calculate my draft with the drive down as I’m about to pass through a canal tomorrow (I know I have plenty of room but wanting to know my draft for the record).

Hi all I’ve a new-ish Suzuki 2.5hp 4 strike for my tender; with a 1L inbuilt tank. I’m off for a cruise up the West coast of Scotland his week and have been paranoid about running out of petrol for it - and rowing is always a pain with 2 people and a small dog in a 2.4m tender. Can anyone...

Hi all I’ve an issue with my Icom M411 VHF (approx 10 years old) which appears to have problems with transmission. Of course it could be the antenna (approx 2m fibreglass whip aerial mounted on the roof of a hardtop 30ft’er). I’m going to have a close look at the cabling / connection to the...
