1991 Maxum - Maxum Boat Owners Club

pintail17 · 05-28-2008, 04:17 PM

I was given a 1991 Maxum 2100 SR? SC? (it's a bow rider) with a Mercruiser 4.3, Alpha 1 Gen 2 outdrive. It was in decent to good shape, I have it about 3/4's cleaned up.

I just finished changing all the Bellows, Bell housing etc, everypart at the transom end and I just picked up all my tools that where thrown about the yard completing the job.

I need/want to change the plugs. But how the heck do you get to them? what do I need to remove?

Also anyone know where I can get fitted mooring cover?

Thanks in advance!

I have that engine, the plugs are right down low you can get to them without removing anything but with the manifolds in place it makes them hard to see

Well thats with my cover off my engine you can work on each side.
if your engine is sort of in a hole, if you know what I mean thats going to make it harder

Without the manifold on you can see the plug holes

Thanks, what else would I need to take off other than the manifolds. If it's just 2 new manifold gaskets and a few hours of extra work it might be worth the time and cost.

This "FREE" boat has got me for $1100.00 for just parts so far.

You don't need to take the manifolds off I just showed that picture to make the position easier to see

You don't need to take anything off other than the spark plug caps

My boat has cost me more than that and I haven't even been on water with it yet

And mine wasn't free

I hear ya.... I've had this lawn ornament for 2 years now...(anyone that is changing the u-joint bellows on an A1G2 buy the sleeve instalation tool it will save you 2 years of frustration)....I washed it once that's the only water it has seen.

Maybe a small extendable mirror will help, I've always shopped in the husky department :roll: so even a kinda medium open is tough.

Finally got the lower unit on last night, ready for a yard test on Friday night, and if all goes well could hit the water by next weekend. If the yard test goes well, I believe all I have left is to:

change Plugs
oil change
new lower gear oil
trim limit adjustment
new battery
polish -->wax -->buff

please add anything I might of missed?

The word 'boat' is actually an acronym = Break Out Another Thousand.

Good luck with your boat, it will all be worth it once you're out on the water!

That's funny! Have not heard that one.

Seems your about to set sail, pintail

It's all about the experience!

2nd yard test was "great success", needed to have the carb cleaned and a couple of other misses. Everything was working except for the tach? Anybody have any ideas? It has a 4.3lx for a motor.

seapuppy · 06-02-2008, 07:08 PM

clean all the contacts on the tach and at the coil....if it still isn't working ..the replace the tach...

Weeeell it didn't sink, but the $#@%ing exhaust bellows came off when I raised the outdrive to trailer.

The motor was FLAAAAAAT no high RPM would just bog down when any throttle was applied.

Just finished changing the plugs, cleaned all contacts in the distributer cap, cleaned coil connections, added a 1/2 bottle of K100, cleaned all fuel lines and filter.

Can I install a water/fuel separator before the fuel pump?(manual)

pintail17 · 07-07-2008, 03:07 PM

Now I'm Pi$$ed, all that work & no change, the carb appears to be flooding on throttle up. Anybody ever rebuild the merc carb 2 bbl with the carb rebuild kits?

Mad Max · 07-07-2008, 04:09 PM

Aside from your ailements, sure is a good looking boat.

pintail17 · 07-07-2008, 06:07 PM

Thanks, It's going to be for sale real soon if I can't these bugs worked out.

Great cruiser 33 mph and rides real nice

seapuppy · 07-07-2008, 07:11 PM

carb rebuild , if your mechanically inclined is easy...I've done hundreds and it's not hard....just time consuming and a memory game.....

where are you located....

pintail17 · 07-07-2008, 08:27 PM

Upstate NY.

I'll take to the guy at Coopers tonight on the $ for a carb kit and ask him on the degree of diffuculty.

Going to check the prop and change the oil tonight and how much gas is the oil. The prop for high end should be 14 1/4 x 23 from what I've read for high end speed, and 14 1/4 x 21 for hole shot. I have no idea what ones on it.

still no tach, so I need one of those to.
