I still don't know what SEI charges to ship.

The new SEI lower units on Ebay right now are the same price as SEI.

That's rectified with a simple phone call right?

the sei drives are identical to mercruiser, every nut, bolt, bearing, seal and gasket is identical, half the price and twice the warranty, made in the USA. I've used several, Barb has one, the fellow that bought Red's Gold blew the drive tuesday the 2nd, they sent hid air freight and he had it Wednsday, back in the water Wednsday evening for the holidays, you can Not beat their price for a new drive, and you get a No Fault warrenty, go figure.

SEI's response:

Hello Eric,

We do not have a dealer locator as you may order directly with us. Our dealers would pay the same shipping and usually pass the cost onto the customer. The shipping to you on the lower unit is 50.00.

Thank you for contacting SEI.

Not a bad deal, actually. Most places mark up their true shipping costs with "handling charges", that doesn't appear to be too bad IMHO.

How easy is it to change a lower unit?

Are there any special alignment procedures or tools needed?

Do I need to take it to a boat shop to have it changed, or am I capable of doing it, with simple socket wrenches and regular wrenches?

At present, I don't have a pump for filling the lower unit gear oil.

The 'pump' will cost you all of $15 from any marine shop...screws onto the top of the qt. of gear lube...and you'll need it for winterizing the boat every fall anyway.

If I could mount my outdrive to my CVZ, anyone can...

Neutron68 · « **Reply #49 on:** July 09, 2014, 10:07:06 AM »

I'd still like more specifics of what it takes to change a lower unit - tools needed, special procedures, etc.

Maybe I can find a video of a Mercruiser sterndrive lower unit change on Youtube?

I just called Dan in Excelsior, he said welding would cost $100.
If welding isn't a good option, he could sell me a working, used lower unit for $300.

Dan is looking like my best option.
I like the fact that he's capable and local - only a 10 minute drive from my workplace!

Eric where are u located maybe I could help I live in Lakeville

Neutron68 · « **Reply #52 on:** July 09, 2014, 01:34:28 PM »

I live in SW Minneapolis. The boat is at the lake cabin, near Paynesville.

At the moment, it is suspended over the lake, on the boat lift. I don't have a vehicle that will pull it, so it stays in the Paynesville area and my lake neighbors tow it to and from the boat launch for me once a year.

Since this year's boating season has been cut short by flooding and no-wake zones, I'm thinking I'll wait until summer is over and the boat is back in the cabin garage to remove the lower unit, etc.

I am on diamond lake just south of you a few miles, and have a towing ready vehicle there almost every weekend. Call me from the cell phone list, or send a Private message I can come up and get you on the trailer from the landing to the cabin. I have pulled the LU of my 88 115 merc, and can help you with that,only takes 20 minutes tops. I will watch for you.

Jason · « **Reply #54 on:** July 09, 2014, 09:23:42 PM »

See, just like that you got two people willing to come out and help without even asking. This group is awesome!

Neutron68 · « **Reply #55 on:** July 21, 2014, 09:42:26 AM »

Yes, this is a very friendly group! I appreciate the advice and help!

Update on speed:
My wife and I were out on the boat yesterday. We were in the main seats in the rough middle of the boat.
The SSV-177 is a 17.0 foot boat with the Mercruiser 120 engine.
I cranked it up to full throttle with the 15x17 prop. The GPS reported 30 MPH (ground speed not knots) at 4000 RPM. This was into the wind, if that matters.

Not to put a damper on things but your RPMs look really low. when I was running a 19p aluminium with a mercruier 120 I was getting 5200rpm at WOT.
Now with my 21P laser II it was turning 4800rpm at wot. Even with my newly built mercruiser 140 I am turing around 4800rpm also. I would check your throttle stop bolt to make sure you are getting WOT and the bolt is not preventing you from reaching it.

I was even getting 4600 rpm WOT on my 120 turning a 21p prop. Maybe a compression check is needed to see if that engine is healthy, and make sure it's running on all cylinders.

Neutron68 · « **Reply #58 on:** July 21, 2014, 11:25:30 AM »

Is the throttle stop easy to find and adjust?

Compression was measured during the repairs last August 2013.
This is from the repair invoice:

CYLINDER COMPRESSION
CYL 1 - 162 PSI
CYL 2 - 160 PSI
CYL 3 - 160 PSI
CYL 4 - 154 PSI

Both the 1978 Mercruiser paper manual and the engine sticker say the target RPM is 3900-4300 for a 120.
