Hi
I am proud new owner of a 301/2002 and have just spent a couple of days getting to know her as much as possible - basically finding out where everything fits. I eventually found the inlet seacock on the MD2010 (at the saildrive), but as I am sure you all know it is challenging to get to. I have worked out how to lie on the floor and get to it "under" the engine. Not ideal, but possible and maybe one day i'll fit a fabricated contraption to lever it from a safe distance. My question is concerned with the "what if" scenario. How the hell can you get a bung in there if something goes wrong ? Am I missing something really obvious ?

We replaced ours with a new hole / seacock that is easily accessible, under the aft cabin. ------------- Cheers, Mark Slocombe, New Rose, Noss on Dart |

Mark
That sounds like a great idea, allowing me to access from under the aft bunk I assume. New hole/seacock, re-route pipes and block original - sounds logical.
I also assume that this was for all the same reasons as I am concerned about.
Was this a big job, ie expensive and/or specialist ?

Also done because the inlet holes on the saildrive are tiny and very prone to barnacles / growth clogging them, hence overheating. Can't recall cost, but of course boat has to be out of water, mine was done by Stephenson Marine at Noss Marina, Dartmouth. I don't think they considered it a huge job. ------------- Cheers, Mark Slocombe, New Rose, Noss on Dart |

Great idea - thanks
Will post update for others if I discover an alternative fix - but I will seriously consider this for the next lift.

Thinking further, I think I am averse to putting a new hole in the hull. Just makes me very nervous.
Has anyone created an inspection/access panel for the right hand side of the engine (looking at it towards the stern) ? I was thinking about a panel from the heads Graeme ------------- Hanse 301 - Deep Fin - MD2010 - MS25S - 2001 |

I have still not worked out a solution to open/closing the raw inlet seacock with ease. I currently have to lie almost face down on the cabin floor and reach an arm (at full stretch) under the engine sump to get to the sea cock. Once I have a hold of t, it is still awkward to close/open - especially open. What do others do ? Am I missing something really obvious that will make me look stoopid ?

Hi, Take the front off the engine compartment---only a few minutes with a small electric screwdriver. Usually only necessary when changing the impeller in the water pump. All the best, and enjoy this glorious summer, Richard

Richard Hopefully you are enjoying the great summer too - at least the topsides are getting a good fresh water wash and anything that is loose or flapping at all is being tested thoroughly with the summer breeze. Not sure if taking off the front works for me. Access would not be much better - so maybe we have slightly different setups. For instance, I can change the impeller with just the steps removed - no screwdrivers required. I only need to removed the top of the engine "box" when I do a service. What does work for me is removing the GRP back panel in the aft bunk/cabin. Not just the inspection panel for checking the gearbox oil - but the full thing. With this off, access is easy. It's just that I do not want to take this on/off every trip. Sounds like Hanse 301 owners just leave the seacock open for day-to-day use - with access only required on "big" or "bad" days.

Graeme,
My saildrive seacock is, in fact very easy to get to. All I have to do is to take the inspection cover of the rear of the engine compartment, it is a curved cover and it is sitting just there on the top of the sail drive. Easy and simple to get to, I have tied a wooden bung of theright size to it, as I have done to all my seacocks, therefore i have the correct size plug to hand at the seacock.
I check my sea cocks regulary and have not had to change any yet due to any Galvanic action. There are, I presume more expert Hanse owners, judging from their post contents on this subject than I. ------------- Hanse 301, tiller steering, Volvo 2010 (10hp)

Holby Your setup is different from mine - mine is on the "floor" coming out of the foot of the main housing on the port side with a small ball valve/cock. Your setup sounds sensible and is news to me. With my small, bolted inspection cover off at the stern, there is no way my arm can squeeze to port of the saildrive box. Hence I need the whole stern cover off by removing 12 or so screws. (or lie face down on the cabin floor ...) Does yours extend the inlet from the bottom of the housing with a fixed piece of pipe or something ? See 34,35,36,37 below Thanks Graeme  ------------- Hanse 301 - Deep Fin - MD2010 - MS25S - 2001 |

I think mine (2020) is similar to Holby's, I'll be down this weekend and take a photo, looking at the above diagram it appears to have been extended. Cheers Stu

Greme, DD ( my 301) is in Scotland (7hrs drive away) at the moment, I will set a reminder to photograph the hatch, and set up when i get back up there in the next 4 weeks......

Attached are 3 pics outlining my dilemma 1) Main access to engine from steps - access to valve/cock is bottom right of sump 2) Zoom of right of sump - seacock lies above cables with cable tie (an arms length away) 3) Access from the back - only good to access gearbox dip stick Just for the record, so to speak Graeme    ------------- Hanse 301 - Deep Fin - MD2010 - MS25S - 2001 |

Don't know if this helps, but I added an extension rod to my seacock which makes it easy to open/close it from just inside the port cabin engine hatch. http://www.myhanse.com/forum_posts.asp?TID=5241&KW=sea+valve&PID=42456&title=saildrive-seacock#42456 Regards F. |

On the 311 series there are 2 additional ply panels to port & starboard of the engine
One in the heads & one in the rear cabin
If you have a flat surface to port of the engine it should be a simple job to fit a round dinghy hatch about 150-200 mm diameter near the seacock in the vertical glass fibre panel. I assume that you have the heads compartment to port so the hatch would not look unsightly.
This hatch cover would be simple to remove or re fit- just half a turn & you could get your arm through OK although you would probably have to kneel on the heads floor to reach the sea cock
Alternatively you could fit one under the bunk cushion just above the gearbox. But then you would have to wake the wife/girlfriend !!! ------------- Daydream Believer- Hanse 311- No GBR9917T- Bradwell Essex |

I Had a look yesterday, sorry completely forgot before, I removed the rounded hatch at the back and within a couple of seconds blindly easily found the handle. For me its the easiest option to close it than. Cheers Stu
