Re: Got me a boat !

Get rid of Whale Tail ! Why?
Trying to read up on changing impellor,but seems complcated.
I think I have a MC-1
If there a step by step manual for checking impellor and upper stern assembly ?

It's all spelled out in A1 Impeller replace.pdf located here.

Spend some time reading the first two topics at the top of this forum. They will explain most everything you ever wanted to ask.

Re: Got me a boat !

Thank you for that Link,very helpful.

I search this site for as much info as I can,amazing site.
However I do get lost and find it hard to know the right spots to click. Thank you.

The answer on the whale fin was not,what I thought helpful.
Chevies do not come with headers but I get 25% more power !

You would think there is a benifit or they wouldn't sell them.

If I get this boat in water I guess I could try my own comparison,doesn't look to hard to remove.

Can we open it to a disscusion ?

I think that has been discussed to death in the Boat Topics forum.

Let's not start a discussion here in this thread on whale tales, that's a whole new topic.

Chevy does sell high performance versions of their cars. You don't get a warranty with them because they know they are not reliable and the efficiency sucks. The whale tail will not give you any power or performance so why use it? Hell even if merc didn't like it don't you think the boat manufacturer would offer it?

Re: Got me a boat !

This is the deal. There are hundreds (actually probably thousands) of hull designs and power combinations out there and every one of them has different performance characteristics. Mercruiser (and every other outdrive manufacture) needed to come up with a design that would work reasonably well with ALL of them. Will a "tail" or plate or trim tabs make a difference? Sure it will, on some it help, some it will be detrimental. Only way to know is try it out, but that gets to be an expensive set of experiments. I have a flat plate on mine and I think it works fine. Smart tabs, or if you care to spend the money Bennett or Lenco power tabs are the way to go IMHO.

Re: Got me a boat !

The impellor directions seem self explanitory However,why does propellor need to come off ?
Has any one made a video yet of this ?
Ive got no hands on yet but was think of trying to contribute,should I try to make one ?

Bellows for a boat this old seems to be a concern in other old boat threads,what am I looking for ?Will I see damage or do things blow up when I try Captain Dave's Maiden voyage ! lol

Re: Got me a boat !

You could change the impeller with the prop on but it makes it a lot easier to handle with the prop off. I think there is a video on youtube on replacing it.

Re: Got me a boat !

go to youtube and put "alpha impeller" and/or "mercruiser impeller" in the search bar and standby by to get overwhelmed. Be advised...."some" of those videos are by semi or non-pros, so take what you see with a grain of salt....compare what you see with the impeller replacement guide (you have one, right??)and ask questions here when you get stumped (or even if you are not stumped).

Re: Got me a boat !

I don't believe it is necessary to take the prop off. If the u-joint bellows leaks, water will get in your gimble bearing and outdrive. The input shaft seal in the upper is not designed to keep water out only oil in. If the u-joint bellows or shift cable bellows leaks, water will come into the boat. Turn the drive from side to side and work the bellows around looking for cracks or other visible damage to the bellows.

Re: Got me a boat !

Also, the U-Joint, and Shift cable bellows can let water inside the boat, and if they tear completely from being dry-rotted, You might get pretty wet watching your new toy sink. :eek:
I know you are excited to get it on the water ASAP, but these guys aren't giving you this advice to make your boat as good as new, it's to make it safe and so you can make it back on the maiden voyage. Nothing worse that watching all that hard work and money go under, or up in smoke/steam because you didn't check/fix something before splashing it.
I hope this doesn't come off as rude, or mean, but it's that important.

Looks like a good find man, especially if the rest of the interior looks like that one seat in the picture.

Another thing that's a good idea to check is to make sure the Coil, Distributor, Starter, and Alternator are all Marine Certified. Marine units are designed to be safer around the fuel vapors, to help prevent explosions. Also make sure the blower works, and the tubes are still in one piece....to get the fumes out of the engine compartment.

Hope all this helps! :)

Re: Got me a boat !

I don't remove my prop to replace my impeller, but it would make it more "comfortable" to handle, and helpful in avoiding damage to the prop while it gets moved around. However, if you've never taken your prop off, it wouldn't hurt to take that extra step as there's grease usually applied to the prop shaft that gets old and needs replaced. Might as well be as thorough as possible, because the phrase "an ounce of prevention...." was written just for boats I think.

Re: Got me a boat !

I designed my drive stand to accomodate leaving the prop on during the outdrive removal from the boat, and for general splitting of the drive. So convenient! Keeps the prop protected, and able to turn if needed (and to hold it/lock it CCW while reinstalling the drive).

Got a picture of the drive stand?
