Re: Thinking of Losing My Inboard

Hi,
I live in Australia and have a 28' cruiser, it originally had a 20HP Panther Diesel, the previous owner removed it and put a 15HP Mariner 4 Stroke Big Foot Outboard on her.
I, personally, don't feel the motor is big enough, the river I cruise floods frequently, and even though extra HP wouldn't make the old girl go any faster, some extra oomph would be really nice in the flood times.
The other issue, which I will rectify in the future, is steering, now the thrust is behind the rudder, not a lot of maneuverability. I don't want to remove the steering from the rudder, as when not using the outboard, still want to be able to steer, looking at a dual cable setup to attach to motor and rudder.
As the motor is a long shaft, there is a lot of leg in the water, and I have not had an issue with the prop coming out of the water, but in saying that, I haven't been in the big blue either.

Re: Thinking of Losing My Inboard

The rebuild was from the local Yanmar dealer. It was a YSM 12, an older 1 cylinder. Parts are available, but expensive. I've done gas engines, including DOHC Alfa engines, so I figured a 1 Cyl couldn't be that bad. After pricing parts, the labor wasn't bad, and it would be done in two weeks, rather than numerous weekends. Even around here winters aren't that long. As mentioned, the Atomic 4 is a good option, as long as reconfiguring doesn't expand the job too much. Several marine engines use Kubota as a base, so parts shouldn't be a problem. My boat was lost in Sandy, and I found a duplicate with a "recently" rebuilt YSM 12, so I ended up finessing that issue.
Good luck.

UOTE=Kielanders;1110625]$5300 seems steep. Did you have the rebuild done at a marine shop?

I've done a few automotive engines (gas). I was going to have the Yanmar (head, block, crank, & piston) professionally remachined (w/ new valves seated), doing the breakdown and reassembly myself from a full rebuild kit - replacing other components (impellers, oil pump, etc) as necessary. I haven't reviewed the manual yet to write-up a game plan.

Something I'm missing, is this harder then it seems on a marine engine?

By the way, does anyone know the Kubota equivalent of a Yanmar 1GM10 for parts sourcing?[/QUOTE]

Re: Thinking of Losing My Inboard

Rebuiulding a 1GM10 is more akin to rebuilding a lawnmower than an automobile. it is a very simple engine. With the exception of the con rod bolts and valve keepers it is basically a two wrench & two screwdriver job.

Re: Thinking of Losing My Inboard

some diesels are dead cheap to rebuild, some have parts availabilty issues and some are darn stupid to fix price wise(volvo)

I just took the decision to dump my palmer p60 inboard gas engine, not cause I wanted to I think they are great, but because I had no way of replcaing a part deemed extinct...

especially overseas where there was absolutely no way of replacing or fixing this part.

I previoulsy had an atomic 4(on another boat) which was simple, dead reliable and easy to service...I dont even have that option now, so I am left with a nice gas tank...clean bilge and no inboard...prop and shaft.

time to either cobble up and electric diy setup or use a 15hp outboard on a bracket...

Im also a firm beleiver in the kiss principle, unlike most common theories around, guys who need more horsepower and huge inboards are those that coastal cruise more and use marinas more...simply because you need to or have to motor into these places either by marina laws or other...

offshore sailors can make do with a solar panel and an outboard easily every new port...I have done it and been on boats that prove this...

when you sail 1-3k miles at a time only to anchor on a nice cove or atoll, or sheltered bay...your inboard is a very very far away thought...not even needed if you think about it...

ps. I will say this, I loved my yanmar2gm when it worked...on a small sailboat however it suffered though, first from corrosion and exposure to the elements, second from too much movement and bad motorsailing from the angles, and thrid I always always had to clean the filters when cruising almost every other day...either water from condensation or dirty fuel even after filtering with a baja filter wasnt enough...

I honestly spent more time working on the engine than checking sails or doing sail maintenance..which if you think about it is ridiiculoous on a sailboat.

lastly almost every port where we anchored at 90% of the boats that where there where either doing something related to engine work or repowering jobs, they ALL had work to do even if the engine was new and they all consumed huge amounts of maintenance when compared to other parts of the boat...think sails, mast, basic rigging, etc...

again sailboat being the key issue here...

peace


cheers

Re: Thinking of Losing My Inboard

So.. why not ditch the engine altogether?

You mentioned you had a 28' full-keel double-ender.. There's an entire class of 28' full-keel double-enders called Tumlaren who manage quite happily with a tiny outboard and a paddle stowed away in the bilge (for absolutely flat calm conditions) and the rest of the time they just sail.

Here's what they look like:





Yep, that's right. No engine. It's a sailing boat..

Re: Thinking of Losing My Inboard

I thought of a few more reasons why not having an engine is a great idea:
  1. No oil leaks in the bilge
  2. No need to spend big $$$ on engine parts and maintenance
  3. No shaft bearing to maintain and leak.
  4. No propeller to foul, get caught on things and slow you down
  5. Less weight aft.
I'm sure others can add to the list..

Re: Thinking of Losing My Inboard

I can play this game too! jajaja

other items off the list:

never get fined for "spilling" (had this happen in santa barbara, one bottle of joy was not enough!)
where to store dirty oil is not an issue anymore
no need for huge matts and cleanup materials, YOUR FIRE and explosion possibilities decrease by a huge percentage(propane leaks cause more fires though)
SPACE! you earn a lot of it!

anywhoo

kielanders I wish you the best finding a suitable replacement, going electric or using an outboard...

I forgot to mention that having an inboard is really dependant on where you cruise and sail...

big currents and tides, and rugged cruising grounds like alaska and the pnw do require you to have extra HP.

the same goes for cruising inside cape horn and such...I wouldnt go inshore unless I had a massive diesel and even a spare kicker just in case...when the wind dies and you have 4-8 knots of tide or current to fight the **** hits the fan BIG time!

PEACE

Re: Thinking of Losing My Inboard

I sailed engine-less on my 7400 lb boat for several years before adding a 6hp outboard. I don't have any complaints about the outboard other than my 1 gallon stinky gas can but took it off today. I guess I just prefer to sail over owning a sailboat that motors everywhere. I have never once had it cavitate on me but then if there is any wind I'm sailing. as far as not being able to get into tricky anchorages I do all the time under sail most of the time, its a big world out there and even if I miss a spot or two there are millions more just like them out there. Where I live we have heavy currents tons of shipping lots of wind or none for that matter and shoals everywhere. I cant even begin to tell you of the satisfaction of starting and ending every journey in complete silence.

Agree totally.

By removing an inboard, the OP has the advantage that the fuel tank is still there and could be re-used for outboard fuel storage if he so chooses.

I can't tell you the look of surprise I've seen on some people's faces when they finally put the sails up after finding their engine struggling to make progress in a heavy tide-way..

Re: Thinking of Losing My Inboard

yup seen that many times...I guess I was being pc about the whole issue...

i have and will always prefer to use my current sailboat as intended, sailing into your dock, marina, anchorage etc...requires practice...thing is so many damn places now dont let you do this...and anchoring out especially in north america is mostly left to permanent liveaboards and or drifters...

once you leave these places you can do what you will being seamanlike and respective of others...

many many times however when cruising I would run into people who really lived by the book not caring about what others or the majority did...too many times I would see people anchor too close to someone simply because they had calculated their scope even before setting anchor...they were so strict it was to their detriment...

same with engine use...anyways I digress

like posts above nothing more funny to me than a diesel screaming into a chop with no sails only to become a sailboat after rasing a sail or 2...seen it so many times I forget to think how dumb it is to expect a sailboat to power through stuff like a powerboat will..

in any case...kielanders you have options which is what this thread is all about I think



cheers
