How do people position themselves to work below deck?

MDboater

This might be a silly question but I find that I can rarely get my body into the position that I need to be in to work on the engine or other systems below deck in my 270FV (single engine).  Most things are too far away to reach when lying on the deck and there is little room on the sides of the engine to crouch down or get in a stable (semi-comfortable) position.  Many times I wish that I could just sit or lay on the engine but I don't see how to do that without breaking something.  How much weight would the exhaust manifold riser support?  That seems like a place to sit but I am concerned with putting too much weight there.  As much as I enjoy taking on boat maintenance projects it seems like I always regret them because I can't reach/see/get at the thing I need to work on.  After working below deck last weekend my arms were so bruised from propping myself up in unnatural ways that it looked like I was in a fight....and lost.  

And a question to people how have owned 270s and moved up to bigger boats.  Is there more room to work on the bigger boats given the twin engines?

I have a 280EC with the 496 engine and generator. Very tight space. I'm not even able to reach my fresh water pump on the firewall to clean the strainer. I was able to lay a cushion down from a chase lounge we had on our porch. I didn't think I was going to ever make it out! Lol. I'm 6'4" and about 250lbs. Talk about interesting!

When I'm in the engine bay of my 270 it usually involves a lot of swearing and the worst is dropping a tool in the bilge and it falls way under the engine.  

Toughest job I had to take on so far was replacing the bravo fresh water pump while on the water and that resulted in some bloody knuckles.

Yeah, how much fun was it getting at those hose clamps and removing the hoses?

I have 300, which is really a 32 with twin V6's, generator, hot water heater..etc.etc.  It is tight in the engine room.  I am currently missing a day of work because I wedged myself in there to work on the genny.  I must have twisted wrong, my back is killing me.  I don't know how marine mechanics do it??!!  Next cruiser is having stand up room in the engine room, or outboards.

@MDboater -  The hard part was scrambling after the plug I had for the hose was too small and I had to run and find something else to shove in there

Tightening the clamps was a B****

Watch and learn from a marine mechanic. Most lay a cushion of some kind across the top of the engine and then lay across it.

I once got stuck behind the generator on my last boat, a 2001 Regal 3780. 5 minutes to change 3 spark plugs, 30 minutes to get in/out.

When I'm working in the bay I always disconnect the hydraulic ram and open the hatch right up.  This gives much more room and save some awkward positions

Its the most enjoyable thing there is, twisted up like a bread wraper, bloody head, hands, arms, sweeting, learned new words, and yes I sit and stand on manifolds when not hot. Yes I sit on top of spark arester . I  Allways disconect hatch and open, unless just checking oil and such. LOL got to love it.

I am able to drop into the engine bay on the port side, get on my hands/knees and crawl around the front of the engine to work on it. Anything involving the starboard/rear area I use a cushion and lay across the engine(like changing spark plugs).... I'm 6' tall and 235lbs.

This is my secret. I dont work on my boat. If I need engine work or any work in the bilge I bring it to my marine mechanic and let him do it. I have beaten myself up trying to access components in the engine compartment. So when something needs to be done I just work an overtime shift to pay for it. Works out very well for me...LOL

@lionelz Make sure you tie off the hatch so it can't swing shut on you.  See my earlier post and on disconnecting the actuator.

I lay across the top of the engines and accept the chest pains that follow for days.

Yoga. lol

I built a 14' gantry and outfitted it with an electric wench to pull and swap my engine... I intended to take it down when I was done, but I think it'll stay put, now...

I have a lot of room to work on my engine in my lil 212, but in all honesty, it takes no more than half an hour to pull an engine out of that boat- so for serious work to be done either on the boat or on the engine, I'm thinking I'll yank it right out and have at it.  

pretty much, the outdrive (six bolts?) in one piece, the engine harness, the power steering lines (quick connects), the throttle and shift linkage, the battery lines, and the four bolts to the engine mounts- drop a hook from the wench, put the engine level bar on the lift-eyes, and zip it north.... seriously- 30 minutes...

I noticed that there was always at least 1 skinny guy working for my marine mechanic....

Plenty of room in a bigger boat!    That being said, I've done and still do my share in much smaller boats.  I just crawl down in and go for it.  Always feel bruised or just sore the next day.

I always have 2 of us when I'm doing it.  Lucky the other day I thought to myself how do I open the hatch if the ram fails (it never has) so I thought I would fit a line to the pin and run it to the inside on my rear seat and tie it of.  Thank god I did a few weeks later the ram failed.  So could not do my engine checks.  My bit of cord worked, managed to pull the pin out from the rear seat and pry the hatch open. My electrical cables had come disconnected so was easy to repair.  Would recommend it to anyone now

Alswag.  I gotta comment on that.   I have a 25hp evinrude on a 15 foot johnboat.   It's a dune buggy on the water.   It's the old style so it has a shear pin.   It's freaking Awsome.   Get too far into the mud and the shear pin snaps saving the lower unit. Takes 2 minutes to change. 
Mad far as positions to work.   I just find the most painful spot not lay on and take Tylenol and beer afterwords
