Fired up the boat on a hose with a bravo 1 getting ready for the long weekend. As someone was watching me put it in and out of gear they said the saw some wobble on the prop. I go back there and look and sure as **** its got some runout. Enough to make the drive jiggle at idle in gear. So either the prop, prop hub, or prop shaft have a wobble. But i dont feel anything while driving besides maybe comming off of idle to plane or at the very top end. But I did my ujoints to take care of that. Haven't water tested since. I was going to have my prop checked out anyway and I will also check the shaft for runout when removed I read somewhere between a maximum of .005 and .010. Ive had the boat for 4 years and never hit anything. My question is will runout/wobble cost any top end speed? I feel like it should have more in it. But i hit 5400ish and it stops seems like it has more. Will wobble/runout increase the chances of prop washout/blowout in the water? I feel like ive had that happen a couple times while owning this thing. Also are there any places that will straighten the shaft and what kind of cost is usually involved if i give them the lower or just the shaft. ]]> Drives and Lower Units Summer89 https://www.offshoreonly.com/forums/drives-lower-units/388071-b1-propshaft-runout-mph-cost.html https://www.offshoreonly.com/forums/drives-lower-units/388036-remanufactured-bravo-1-outdrives.html Thu, 14 May 2026 16:25:53 GMT any reputable companies selling remanufactured bravo 1 out drives ? any reputable companies selling remanufactured bravo 1 out drives ? ]]> Drives and Lower Units 26sonic https://www.offshoreonly.com/forums/drives-lower-units/388036-remanufactured-bravo-1-outdrives.html https://www.offshoreonly.com/forums/drives-lower-units/388023-outdrive-finish-protection.html Wed, 13 May 2026 17:00:11 GMT any suggestions on keeping a outdrive finish like new when leaving in fresh water for extended periods of time ? have all the necessary zincs . any products to apply ? any suggestions on keeping a outdrive finish like new when leaving in fresh water for extended periods of time ? have all the necessary zincs . any products to apply ? ]]> Drives and Lower Units 26sonic https://www.offshoreonly.com/forums/drives-lower-units/388023-outdrive-finish-protection.html https://www.offshoreonly.com/forums/drives-lower-units/387991-swapping-bravo-2-out-bravo-1-a.html Sat, 09 May 2026 16:52:55 GMT Taking on a little project boat, it’s in useable condition, but has a few things I want to address.

Taking on a little project boat, it’s in useable condition, but has a few things I want to address. One thing is the drive, it has a Bravo 2. It works, but the boat will never reach its potential with a Bravo 2.

What exactly would I need to replace if I wanted to swap in a Bravo 1? Is it just a lower unit change? How should I go about selecting a gear ratio? It’s a 22’ boat with a 502, aiming for 60+mph on top end. ]]> Drives and Lower Units Powervalve https://www.offshoreonly.com/forums/drives-lower-units/387991-swapping-bravo-2-out-bravo-1-a.html https://www.offshoreonly.com/forums/drives-lower-units/387935-bravo-xr-bearing-carrier-seals.html Sun, 03 May 2026 00:43:59 GMT Is that rubber inside of the blue housing against the shaft an important seal?

Is that rubber inside of the blue housing against the shaft an important seal? Boat has been sitting for a few years, I just noticed they looked cracked and deteriorated when draining the lower unit oil, should I be changing these before it goes in the water for its first test run in 3-4 years? They were not leaking, oil showed no signs of water intrusion.
