ALPHA 1 strength?
 

Not sure if this is the right section or not, but I'm wanting to get other peoples opinions on how strong an ALPHA 1(87 not a GEN 2) outdrive is? Now that I've got my 315HP MERCRUISER purrin, I'm wanting to put it in my 25' SEA RAY CC. But I don't know if the original ALPHA 1 will hold up to it or not. It's currently got an ALPHA 1 in it that is coupled up to a 260HP 350 that is locked(improper winterazation). It's a 1.5:1 gear ratio and appears to be in nice shape(probably not original, but the hour meter only shows 340 original hours).

So SKOOLZ what you think, yey or nay?

my 250 FC Sea Ray has an Alpha I factory with a factory 310 HP Merc. GM 350.

What year is yours? Have you run it at all with the ALPHA1 to see how well it holds up? My 250 SEA RAY is the same basic model you have. Heres my model from SEARAYS archives.

mines a 86 SR250FC

Re: ALPHA 1 strength?
 

Not a member, I'm still waiting on my title. The FC model is very similar to the CC model from what I've seen. I just don't want to saddle this 315HP gem down in it and have my ALPHA1 go KABOOM.

Re: ALPHA 1 strength?
 

lol it should do fine. the maindifferencein the CC and the FC is the FC has all fishing boxes and live wells plus more walk around room. The FC stood for Fishing Cuddy. you don't need a title to be a SeaRay owners Member you only need you HULL ID and your model number off the transom. if you call sea ray give them your hull ID they can tell you the month blt. yr blt. location blt. dealers sales location and all that boats life till sold by dealer.

This doesn't make me feel good. MURPHY's law should be called THEFERMANATOR's law. If it can go wrong, it will for me. I'll give them a call with my hull I.D. though and see what they can tell me. I've got a buddy with a pair of 2001 TBI 260HP motors for $700. One's free and the others seized, but I may go that route to keep the HP down to the old ALPHA drive. But this 315 sounds SWEET!

Re: ALPHA 1 strength?
 

it's not but 5 more HP than my factory motor plus it's not the HP that will break your lower unit it's the torque. what are they on that as in difference wise?

Re: ALPHA 1 strength?
 

It should be just fine, as long as there is gear oil in the outdrive ( take it from me ).

Re: ALPHA 1 strength?
 

No camera, I'm slow to catch up on technology. I finally got high speed internet last MONDAY, cameras next on the list though.

I'm wondering how much I can get for the BORG and WARNER VELVET DRIVE that is currently on this 315HP engine? It's got under 64 hours of verified use on it. Maybe I could part out the ALPHA and B/W and get a nice BRAVO.

My wife just said we should hook up a webcam to have video conferences with my kids in Ca.

Could you imagine if the technology was set up
so all of us on the site could converse with webcams. :o :o

that Alpha one should be fine aas long as your not trying to pull up a bunch of slalom skiers. Mercury used the Alpha 1 gen 1 behind some 330 hp 454's in 85-87 with limited success( used 1:32 gears). The main difference( strength wise) between the Alpha 1 and Alpha 1 Gen II is the absense of the o-ring groove on the verticle drive shaft. Lots of gen 1's would break off at the groove under high load or contact. You can update your gearset with the HD 1:50 to 1 gears( stronger than the 1:32's), but by the time you pay someone to install them and pay for the parts, you could buy a complete new drive from sterndrive.com. I haven't used any of their drives, but the people I know that have used them haven't had any problems. The best thing to do in your case would be to run the Mercury High Performance gear lube( the green stuff), add a gear lube monitor( they make an external kit), and posibly install a drive shower to keep the upper unit cool. If taken care of, that alpha will be OK, I built an Alpha 1 SS for a 21 Sleekcraft, that had a blown bigblock in it, I personally drove it to 101 on radar. The guy took it easy on the drive, he'd never hit it untill he was running at least 65, and once a year I'd tear down the upper( he had the 1:32 to 1 gear set) and check the clearances in the drive and reshim if needed. When he sold the boat it was still running the original gearset.

By the way, use good grease on teh input splines, and keep a check on the alignment, pull the drive at least once a year( or 50 hours) and put more grease on the splines, and check the alignment. With heavy boats I've seen a lot of coupler failures from lack of lube, the strain of the heavy boat tends to work the grease out of the splines

Spare parts is pretty much right on about the alpha,
it will hold up fine with your horsepower, and hes got a good point especially about the spray cooler and drive fill resivoir, most failures occur in the upper gearcase, due to poor/cheap oil breaking down under heat, and low oil level, dont get a big old bravo there heavy and suck up a bunch of horsepower, of course you could go all out and get one of the merc. speedmaster series, (assuming money is no object LOL)

Re: ALPHA 1 strength?
 

I've got a buyer for the boat, but he wants a BRAVO with the 315HP engine. My 315HP engine unfortunately has no provision for a shift interrupt switch and adding one will put the ECM into safe-mode(as per a MERCRUISER tech). I have a BRAVO 1 outdrive and gimble that I got reasonably already, but I'm really trying to talk the guy into taking the boat with the 98 260HP 350 TBI motor I got with the ALPHA outdrive. I'm trying to convince him the boat aint worth the $9-$10K he'll be sinking into it with the other engine and a BRAVO. But I aint buildin it for him until I have the cash in hand.
