Cummins Mercruiser (VM) 4.2l, 320hp diesel year 2006, Bravo 2 leg, Bertram 25'. So went out in some moderate conditions the other day. Decided early that this wasn't a great day so turned around around 10 minutes. On the way back in, around 3300rpm, the engine struggled to maintain revs...

Dear forum, I've just 'celebrated' 3 years with my Bertram 25, and am now finally moving on to fixing the accessories and various other bits that I removed after over 1000 hours doing more essential things. Had a good summer's use. The below pump has always just been there, connected to the...

Gave this a try this summer, in the Med. Boat was launched early January with velux on the leg. Started putting the bag on in early July when I noticed the first signs that there was some growth. Wow, I knew it'd slow down the growth rate but it's stopped it entirely, and this is 28°c water...

So, in November 2020 I went ahead and purchased a battered, neglected Bertram 25 which had been left to rot. She was a mess, a total mess. I went for a sea trial and found the following wasn't working: 3 bilge pumps Upper fly position (neither the steering or throttle or changeover system) Nav...

After spending what seems like 3 months preparing the hull of my Bertram 25, I will soon be embarking on a DIY roll & tip job. I've done this before on small things such as hatches, tables, with a reasonable degree of success but I want to make a really good go of this. Any advice or tips...

Hi all, Quick question - I know there are differences between the Bravo and Bravo X drives......but what about in the transom assembly? I have to change my transom assembly. I checked the serial number of the current TA and it's a Bravo 1X. Is there any difference between a regular TA and the...

Dear forum, Got a leak, a drip every 2-3 seconds, coming from what appears to be the top of the exhaust on my Mercruiser Bravo. Is there anywhere other than the steering pin that could leak only when the engine is running? Some points: 1) steering pin is stainless and new, installed Feb...

Hi forum, Tomorrow I'll be having a go on a twin jet operated boat. I've used single jets a lot, which are fantastically manoeuvrable, but I've never tried twins before. Any tips from experienced users? Barring the "bow goes the way of the wheel whether ahead or astern" rule , are there any...

Dear forum, I've wondered for quite a while what the point of this tube (shown with the red arrows) is. Goes from the rocker cover, passes by the oil separators (?) and onto the turbo air filter. And, 2nd question....can a dodgy wastegate reduce turbo output? Reason I am asking is as...

Looking for the following part: 898101505, alternator, which is no longer available - bit of a long shot but does anyone know of an equivalent? There are no details stamped on the present alternator which, after producing no charge, I had tested and has died.

Dear forum, Got a strange problem. My Mercruiser 4.2 diesel wouldn't shut off when I turned the key off the other day. At the time I just starved it of fuel and she shuddered to a halt but today I managed to disconnect something behind the dash panel (I'm not entirely sure what) which stopped...

Dismantled the upper gear housing on my Bravo 2 leg as the gear change was very very stiff, having checked both the detent ball and the gear shift cable. The cone clutch is worn down and needs replacing. However, it's the old model that is discontinued (pre-2000). The part number is 807375A2...

Got a Mercruiser VM 4.2l diesel hooked to a Bravo leg, both 2007, but I can't tell whether it's a Bravo 1 or Bravo 2. Are there any significant differences, observable visually? Previous owner doesn't know as the dealers did everything for him. Dealers I can't get hold of, for the moment.

Went to have a look at a boat I am interested in recently. I am not all that familiar with outdrive setups - I've had Alphas before but many years ago. The boat is going very cheap as it needs a fair bit of work (mostly aesthetic) but I would have to pull the leg off anyway, which isn't a...

Looking at a boat fitted with the above engine., year 2007, 500 hours. Having done a search and decent read on here, reviews seem mixed but the most recent thread is a few years old. From what I can gather, parts seem reasonably priced and fairly available. Any more experiences? Thanks

I'm looking at buying a boat in the Med (France or Italy). Nothing big, 25ft or so, which I would keep there (Italy most probably). I'm from Jersey, Jersey resident etc so anything I buy would be registered as a Jersey vessel. However... If I buy a French or Italian flagged vessel (with VAT...

Hi, The check engine light on my suzuki DF60 is flashing 3 followed by 2, which I believe is a bad MAP sensor. This came out of the blue about a week after a service and the engine runs as well as its ever done. If the MAP sensor is dodgy, what are the consequences of continuing to use it? Is a...

The check engine alarm needs reseting, anyone know how this is done? I don't have the manual and it has just been serviced (last week). When the oil light came on last year, the reset pattern involved pulling the killcord swich in a certain order, presumably this is the same?

Just ordered a Lowrance iFinder plotter and it comes with free NauticPath cartography. Any good?

Hi all, I'm sure someone out there will be able to help with this. When lowering the engine the other day, the tilt process slowed then eventually stopped when the engine was at the top of the power trim (when the trim motion slows down), and there it remained! Now all I get is a click when I...
