How Easy to Mount/Dismount Outboard Gas Engine?
 

I would like to know how easy to mount or dismount an outboard gas
engine -- let's say a 40HP motor. I assume I need a carrier to hold the
outboard motor while I mount or dismount the motor. My questions a

- Is this a one man job?

- Do I need a lift? How small a motor can
we man-handle it without a lift?

- How many hours should I expect to spend to mount
or dismount an outboard?

- Is this something that we can do frequently on
the same boat without creating a lot of wear
and tear? Let say doing this once a month.

The reason why I am asking this is that I would like to use one boat
for both in electric-motor-only lakes and lakes that allow gas engine.
I plan to dismount the gas engine when I go to electric-only lake, and
then re-mount the gas engine when I go to lakes that allow gas engine.

I prefer to use the same boats in both areas instead of two different
boats. The reason is that I don't want to buy two boats, two trolling
motors, two set of batteries, two fishfinders, two trailers ...etc. If
I only have one boat, I can outfit the boat with good stuff. If I have
two boats, I will have to put so-so stuffs in the boats. Moreover, two
boats takes more storage spaces.

Of course, if frequent mounting and dismounting is not a practical
idea. I will have to settle with getting two boats.

Any idea? Thanks.

A 40HP often is bolted to the transom, this takes some more time
to install than a smaller engine. Installing a 9.9 or 15HP can be
done in 5-10min by one person. A heavier engine might need two
persons or a hoist.

But using an electric motor on a boat designed for a 40HP will
give you very little speed.

How much longer time to install a 40HP than a small engine? Would you
please give me a ball-park figure? Do we need any special expensive
tool that a person is not likely to have?

Sound like this is a two-persons job...

Actually, I am just guessing when I mentioned a 40HP gas engine. I
don't really know how much horse power that I will put in a 18-ft boat
that I am looking for. I use that number just because Tracker web site
states that 40HP is the maximum horsepower that we can put in his 16-ft
boat alumimum deep-V boat. 40HP probably represents the upper limit of
what I may put in the 18-ft boat. Actually, I don't intend to put in a
large gas engine in that 18-ft boat; on the other hand, I plan to put
in as large an electric trolling motor as I can find in that boat.

Thanks.

Jay,
I think you need to:
A - look at the engine weight
B - consider your options

Look at manufactures sites for engine weights.
Most 40hp catagory enines are about 250#.
(A man can lift and carry it - but not far.)

A boat designed for 40hp is going to be disappointing with a trolling
motor for power.

Thinking is the cheap thing to do....

Yes, you are right. I should decide on the hoursepower that I will put
in the boat, then find out its weight, before I will determine whether
I can mount or dismount it.

Thanks.

If you have a hoist, one person can do this, but two persons are more
convenient. Time, probably 30 minutes.

The tools you need are a couple of wrenchs. And for the first time
installation you need to drill holes for the mounting bolts. (Usually 4
holes.)

By the way, I have a 40HP Suzuki 4 stroke. It is 108kg, to heavy for
even 2 persons. A hoist is needed, but the I can install it alone. But
it is very convenient to have someone holding the wrench on the other
side when I am tighten the bolts.

Not trying to be a smart azz; how about a jon boat to use on the no-power
lakes? you can transport cartop, it'll move pretty well with trolling motor,
light and easy to carry. And you can flip it upside down on the power boat
for storage.

Actually it is a valid advice. I have thought about using a 15-ft
canoe. But I have decided against this idea. The reason is that I need
to mount something to shade me from the sun. I don't think this is a
good idea to mount something over a small canoe or a small jon boat --
I am afraid that the boat will become top heavy and flip. Considering
the fact that the most likely time for me to use the boat is Friday
afternoon in summer, shade is very important to me; otherwise, baking
under the sun would surely take the fun out of fishing.

The other alternative is to use a small 12-ft raw boat that I may be
able to mount a bimini top on it. But I would need to find a storage
space for it in addition to finding storage space for the 18-ft boat
that I want to fish with a couple of my friends with.

And two boats also means more expenses.

I think if I cannot mount/dismount the engine easily, I may decide not
to visit those electric-only lakes, and stick with lakes that allow
outboard engine. I still need to find out if I can still use the boat
in electric-only lakes if I can simply tilt up the engine and only use
the trolling motor.

There are actually, quite large umbrellas available. Light nylon for its
shrouds. Just keep an eye open for squall lines.

Only two boats in your future? Piker. You won't get a chance to wear a
Commodore's scrambled eggs that way.

Not sure how relevant this is but, I have a 12ft Zodiac inflatable with a
15hp 2 stroke Mercury outboard (weights about 35kg) I use it as a tender
to a sail boat. When I'm launching from the shore, and I can walk up behind
it, it's easy to fit. When I'm lauching it from the sail boat and I need to
lift it off the deck (4ft freeboard) , and mount it on the transom from
aboard the dinghy it's much harder, but not impossible. I working on a
method of lowering it with the boom direct onto the transom.

How about a dedicated little outboard motor crane. Lots of
folks make them, Garelick (I think) got a practical sailor
"best buy"

I have thought of that, but I've already got a main boom and a staysail
boom. I like to keep the number of "bits of kit" to a minimum, so I'd prefer
to use one, or both of these. I think all I'll need is a spare block and
tackle, and a means of holding the boom steady.

You should be able to use the boomvang clipped to a stanction base
to pull the boom against the mainsheet and hold it close enough for
what you want.

I would use the mainsheet as a tackle to lift the engine, with a
sling around the boom to slide it over the side. An old piece of
rope would take the normal place of the mainsheet, to stabilise the
boom.

Outhaul and reefing lines might work for you as a means to slide the
main tackle sling over the boom. I guess you'd have to remove the
main sail.

I always tied a safety line to the outboard and backstay, just in
case the outboard went for a swim during the transfer between boats.
