    Anybody Have Any Luck Epoxying Exhaust Manifold Surfaces?

    1998 Merc 7.4 Bravo One cylinder had a stuck valve due to manifold failure/water intrusion into exhaust ports. So I took off both of my heads and brought them to a machine shop. After jet cleaning, they say overall the heads look in pretty good condition. The major issue is that a few of the...

    Mercruiser MC-1 1.32 Drive

    Serial Number: 6267140 Ratio Stamp?: H So I have this sterndrive that I bought a few years ago. Back when I bought it I didn't know any better and was told it was an Alpha Gen 1 drive w. a 1.5 ratio.

    Just Replaced Gimbal Bearing, Still Making a Noise?

    Just replaced a gimbal bearing and two other people as well as I agreed the old one didn't feel bad. So I re-install the drive, and the sound didn't go away. Could it be drive shaft u- joints if I don't remember feeling any play in them? I just can't imagine what else could be making this...

    How concerned should I be that my open eye leaf springs are barely hanging on?

    Recently replaced my leaf springs. Pictures tell the story. Can any adjustments be made? On a side note, the trailer was put in water ONCE (saltwater), and rust and salt are already attacking the leaf springs and zinc hardware. *SIGH* :facepalm:

    Interchangeability of Single Engine Top Mount Controllers

    BOAT: 1993 Chaparral Signature 270 w. 7.4 Bravo One Hello Awesome Mercruiser Forumites! I've come to realize that one of the least liked - maybe my SINGLE least liked - things on my boat is the controller. It feels as though I'm stressing the cables when I move it forward and backward. Then...

    Filling The Gaps On A Trailer That Wasn't Made for My Boat

    Happy Sunday Evening! :joyous: I bought a used 30' galvanized trailer for my 1993 270 Chaparral Cabin Cruiser. After loading the boat onto the trailer, the boat sat mostly on the outer chines and also made nice contact with the bunks on the upper third of the boat. However, the middle rear of...

    6 Lug Trailer Wheels vs Auto Wheels

    Hello. I recently bought used a 30' dual axle galvanized trailer rated to 10k lbs. It came with 6 lug size 14.5" rims. It also came with "LT" light truck tires instead of "ST" trailer tires. So I'm looking to possibly upgrade to a ST tires. But I'm bothered by the idea of sticking with such odd...

    Hmmm....I blew the spark plug insulator right out of the thread jacket....

    Boat: 27' 1993 Chaparral 270 w. a Gen V 7.4 carb'd engine w. a Bravo 1 drive Last Friday I opened up the throttle in the Ocean and was humming along at 35+ MPH. Probably doing 4200 - 4500 RPM (My tach doesn't work...sigh). About 8 minutes into it I heard a loud "boom/bang" noise, then a super...

    Questions About Installing A Plate To Access Steering Arm/Nut/Pin Externally

    I have a friend who is refurbishing a 90's-era 24' Maxum. It has a Bravo 3 outdrive. There is lots of evidence galvanic corrosion. The worst of it is about a 1.5 inch hole in the external transom housing assembly right where the steering arm is located. You can see the nut, washer, etc. So he...

    Need Help w. My General Electrical Setup

    I bought a 27' Chaparral last January and immediately started rebuilding the engine, outdrive, and transom assembly. Well I'm finished w. all that now and I'm realizing I kind of forgot to note the electrical layout. As you can see from the pictures, I have two starting batteries that are...

    I have a Mercruiser Bravo 1 and I just bought a Solas Prop w. a Rubex 107 Hub Kit...

    Bought it on Craigslist. Was mostly interested in the prop and was intending on buying a Merc hub kit. The RBX 107 hub kit is marketed as a Honda specific hub kit. But when I got home, I put the hub on the Bravo shaft and the splines mated perfectly. It's my understanding that Mercruiser uses a...

    Need Resources on How To Shim And Set Gear Lash On A BRAVO Upper Gear Set

    Last January I purchased a 27? 1993 Chaparral Cabin Cruiser for cheap. Reason it was so cheap was that the sterndrive was a Bravo 3 and it had succumbed to a devastating episode of electrolysis. There were holes straight through the gear case. Amazingly, the upper gear case gears were...

    Engine Mount Holes: Anything to be done before putting the engine back in?

    I?ve spent the past few months taking apart, grinding off rust, painting, then putting back together a 1993 Bravo 7.4 engine. The boat is a 1993 27? Chaparral Signature. It?s getting near the time to put the engine back in, and I?ve been wondering about the engine mount holes. There must have...

    How to Test A Temperature Monitoring Alarm Switch

    I have a ~1993 Gen V Bravo 7.4 engine I'm working on. I'd like to make sure that the Temperature Alarm system is working properly. I know that the Oil Alarm works off of a normally on circuit, so that when you put the key in the ignition the oil alarm circuit is "ON" and so you hear the buzzing...

    That Reddish Brown Thread Sealant On Oil and Hydraulic Hoses....

    Does anyone know what brand or product this is? I get the feeling it performs better than typical teflon tape or that Permatex Thread Sealant. Thoughts? If I recall this stuff is also used on the fuel fittings, no?

    When The Wheels Fall Off....

    Just bought a 1998 23 foot bow rider this weekend. It has a galvanized two axle King Trailer (they market themselves as the "saltwater trailer" company). I *believe* each axle is rated to 5200 lbs. These are torsion axles with a 6 lug pattern and heavily rusted drum brakes and hub assemblies...

    Happy Sunday! :happy: I have a 2002 Ford Excursion tow hitch setup that has a factory flat 4 pin connector (as well as a round connector that I've never used). Well I just bought a trailer that has surge brakes as well as a 5 pin connector. I'm reading online that if you retrofit the vehicle...

    I recently called Mercruiser Support to get some information about a used sterndrive I was going to buy. This is probably common knowledge to some people here but the customer service associate at Mercruiser told me.that Mercruiser does not choose engine/sterndrive combinations; that function is...

    Two Questions About A Mercruiser Raw Water Pump

    Hello. Working w. a 1993 Bravo 7.4 engine (SN: 0F009622). From what I understand this engine originally came with a two piece seawater pump. But mine seems to be a one piece pump...so I guess this one isn't the original one. Anyway, I've been trying to get this boat started after 6 months of...
