Confused!!! Need help/advice/opinion on what to do with Speedmaster II's!!!!!!!!
SubscribeQuote:
Best money you could spend on drives is for the Konrads. How much do most guys spend on drive repairs every season, $5k-$10k? What do you plan on spending on used (and unknown condition) XRs, transom units, steering, etc. $10k? Are you going to put drive shafts in, move the motors back, etc.? If you have headers for TRS' and you move the motors then you'll need new headers, $10k. Plugging the transom and re-cutting for XRs'? If you have a shop do this it's another $10k depending on where you live.
The conversion is going to cost you $20k minimum by the time you're done plus you'll have the repair cost of XR's hanging over your head.
I see a nice pair of Konrads HERE for $15K complete!
Sounds like a better deal, you could bolt these on yourself in a weekend no problem.
Redoing the transom is no problem for me and one of my best friends, he owns a body/fiberglass repair shop, to do by our selves. Originally Posted by Lofty

I would have to run drive shafts for both motors but I dont mind that if I can get back 20% more hp out of the deal and ditch the tranny's. I don't want to move the motors back because I have found through research that it upsets the weight balance and causes some planeing and porposing issues. Now I might have to move them down in the hull to line up...
OR PLEASE ANSWER THIS QUESTION FOR ME
can i run the drive shaft at an angle just like in a car???As for the weight of the boat, Approx 9000lbs. One of the guys I run around with has A 38' Cig Top Gun with 725hp blower motors, should weigh as much or more, and has never had a problem, other then when he hit a tree lol, with his XR's..
The boat actually just has merc mani's with rubber tubes all the way back from the elbow to the tip, which I would like to replace at some point anyway.
Now you mentioned steering... I already have a fully hydraulic steering setup on the boat so I am guessing I would just need to modify that to work with the xr's, is that correct???
Oh and please don't take this as I am downing the quality or anything about the Konrads, in fact I have hurd nothing but good things about them. I am just a boater-on-a-buget!!! I try to get the most bang for every buck I spend!!!
You absolutely, positively will not lose anything even remotely close to 120 horsepower (20%) on a boat with 72C transmissions. Maybe 20-25 horse. The Bravo isn't going to live long at 600 HP. There's a reason Merc doesn't sell them with engines nearly that big.
With all the money you're going to spend trying to rig up driveline Bravos (input shafts, drive shafts, rear mounts, u-joint drive plate, etc) you'll be well on your way to a decent set of drives- and nobody's giving away XR's.
And no, you can't angle the shaft.

The power loss is just what I was told.... If it is only 20-30hp then no its not really worth it I will agree! Originally Posted by Chris Sunkin

For now I am just going to find a right hand rotate SSM II and be nice to them for a couple years... maybe by then I can afford the Konrads.

Just trying to put you on the right track, no offence here trust me. Originally Posted by bigo181979

BTW I have a set of XRs for sale but they wont last long on a cat that heavy.

I have only ran the boat full out a couple times, had to beat my boys $100k Top Gun the first weekend out with my $30k Kitty, he was pissed!Originally Posted by Chris Sunkin
Lots of oil changes and be very careful about your exits and entries on jumps. The lowers are less than robust.
Anyway it torque steers so dam bad that it is almost unplesent and a bit scary to drive it much over crusing speed, especially for any extended period! So for now I just cruise it and occasionaly i will run it hard!
Also the lake I am on the majority of the time does not get really ruff, Its a small local lake so I am not to worried for now about exits and entries.
But thanks for the advice I will keep that in mind!
Maybe you could send your LH drive somewhere and have it changed to RH? I believe it is just the gears in the lower unit that dictate the direction of drive rotation. You might try Galen at Speedmasters. He was a huge help with my SSM 3 drives a few years ago. He seems to keep a pretty good inventory of the older stuff.

Called him already no luck! You are correct about the gears but I would rather get another drive that way I have a spare.Originally Posted by waterbum
