I have 22p props which should theoretically be mid wot range with 2.0 and top rpm wot with 2.2. I can pack either setup since I have both upper units.
My concern is that one spins pretty easy (2 fingers on yoke) while other i have to grab with whole hand and twist significantly to spin...
One small difference in upper b1 is 27x32
B3 is 23x30.
Basically 1.5 vs 1.65 b1 or 2.0 vs 2.2 b3.
Not sure if this could cause higher resistance as ratio is higher in my b3 upper. But difference is significant
I'm in process of replacing bravo one for bravo 3.
Got bravo 3 in 'decent' condition, cleaned it, repainted...
Just pulled bravo one from the boat and when in neutral on bravo one upper shaft that goes into coupler spins pretty freely, while bravo 3 have some resistance.
Since uppers are...
white aluminum oxide, I haven't blasted it myself, shop from which I purchased the drive did.
I took back cover to clean cavity where shifting mechanism is and seal seems fine. pressure tested few hours at 10psi... rotated shafts few times, all good.
Ye, 2 part paint would be great, but I...
I'm planning to install drive in few weeks, and pull it out again in April for inspection and maintenance. so will let you know how it holds.
I read everywhere that factory paint is much more durable then anything diy, and it's best to just clean/#scuff old paint and prime/paint it.
On first...
outdrive is painted, looks solid.
I have small amount of rust on yokes, surface, no pitting, is it ok to wipe it with rust remover?
I purchased this outdrive, wasn't on my boat previously, but it doesn't look like water went through bellow, as the surface rust is only on one side. it was stored...
Haven't thought about the prop clearance, good point, will check it. My concern was that they might left it exposed for mercathode to do it's thing or something.
I'm on a freshwater lake, so I thought this preKote things as prep should work fine, wasn't confident using alodine on a driveway...
I'm preparing outdrive for painting and noticed that bearing carrier is originally not painted.
Since the drive was media blasted, I believe whatever protective coat it had is gone.
Is there any reason not to paint it together with the drive?
Regarding painting process, idea is following. 1...
sorry for late reply.
there were two issues.
1. switch behind tachometer was positioned for 6 cyl engine instead of 8.
with this fixed actual rpm wot was 4400.
2. since speed at that rpm was slow, i figured prop is slipping too much and changed it to 4 blade. It's much better now.
I had similar situation once on another boat, didn't perform well with tabs down (usually planed much better with them down).... I anchored and asked my wife to click the switches and tabs were stuck up, after pulling them down with hands hard few times, they started working again. Maybe your...
That's 300hp, so original equiped was 16x17.
I believe it would be hard to find exactly same model of prop, and even then other prop despite looking good is probably off the original specs, so I would replace both once boat is out of the water.
Does anyone know if these are much louder then stock manifold/risers?
I have them on 270dancer single 7.4 and it's really loud above 3000rpm, it does sounds healthy and I would love the sound on go fast, but it sounds a bit too much for a cruiser.
I'm trying to figure out if loudness is coming...
I would keep dancer, cruiser is the most practical for all around use. I would buy and older repowered Baja 23-24' for some watersports or just riding around and keep cruiser for most days.
I saw couple in my area im $20k range with new 502 merc.
I would try to swap props and I'm positive, problem will occur on starboard with port prop.
They might be repaired and have same pitch, but due to previous damages machining might took more material of starboard prop toward the edges, so it provide more slip and engine is get chance to spin...
On my '99 270, PO replaced door track, but didn't put helm back correctly and door were rubbing on helm.
I removed the help cleaned tracks when I was at it and reinstalled, it's not as hard as it might looks.
If you have problem with bottom only.
1.slide door in, remove outside screws.
2.slide...
update: I tested 14x19 4 blade Hustler and it's too much pitch for my application, wot went down to 3600, without trimming I didn't want to push it to hard, so went back to 15x15.
Surprisingly it didn't jump out at around 3200.
with 15x15 Lowest plane speed 20-21mph@3400, sweet spot seems to be...
