    Broken Forward Gear? Cause?

    Okay I watched a video on how to take the lower apart to find out what caused it to grenade. Nooooo thanks. I'm not about to buy 7 or however many special tools for this thing to still be hard to take apart. What generation used Bravo drives should I be looking for? Should I avoid the first...

    Broken Forward Gear? Cause?

    Yes my dad bought it new in 1979 and ran it till 1985. It then sat under tarps for 32 years till 2017 when I put it in the water. I took the top cap off the upper unit and I do see a little rusting in the top bearing and in the valleys of the upper gear. The little bearing on top spins freely...

    Broken Forward Gear? Cause?

    In the video, I go from neutral to forward, to neutral, to forward, to neutral and then rev it in neutral. Mercruiser 228 drive (1.5:1) with a drive shower installed and custom built 383 stroker at roughly 420 HP. A couple of questions: 1. Does this sound like a broken tooth in the FWD drive...

    Screeching Noise from Frankenstein 383

    It was an Edelbrock 1409. With multiple people in the back of the boat, the boat would sit too low in the stern when trying to get up on plane. A slant wedge spacer for the carb would have probably solved that or I heard you can put some sort of plates in the bowls to keep them from spilling over.

    Screeching Noise from Frankenstein 383

    Mine has held up okay, but it is far from perfect. Like I said, I would not recommend it to just anyone. If the carb is working for someone, I would say stick with their carb. The Sniper is Coast Guard rated, but with that said, they didn't take the necessary steps for making it boat ready. The...

    Engine mount nut sizes

    My 5.0L from 1985 was a 1-1/16" if that helps. The newer'ish 383 MAGs use the same size.

    Screeching Noise from Frankenstein 383

    The exhaust crossover ports are covered in mine. I have an AFR Eliminator Dual Plane 4150 intake on it which does not have crossover ports.

    Screeching Noise from Frankenstein 383

    I have had the Sniper for about 4 years. I had it on the last engine in this boat. I like it much more than the carb, but I wouldn't go recommending it to anyone that wants to ditch their carb. ESPECIALLY in a boat since the biggest downside of it seems to be that the display unit it comes with...

    Screeching Noise from Frankenstein 383

    I am not really sure. I read that the square bore gasket acts like a blade of grass between your thumbs when you blow on the blade of grass. It is kind of what it sounded like, but not really sure. All I know is that I'm boating again!

    Screeching Noise from Frankenstein 383

    Put a 1" 4 hole aluminum spacer on it with a 4 hole gasket above and below the spacer. Put it in the water today and the screeching is gone! Thank you all for the help!

    Gimbal Hinge Pin Bolt stuck/stripped

    You can try spraying it with kroil a few times in a 24 hr period, then use a screw extractor. Heat up the aluminum with a torch, then immediately use the extractor. Some places you can rent these at a auto parts store for free. If that doesn't work, weld a stainless bolt onto the hinge pin.

    Mercruiser 3.0 won't "lock in"

    SEI is a brand that sells more affordable aftermarket replacement drives that are still quality. OEM Mercruiser drives cost more or are no longer in production.

    Bizarre IAC reading

    40 knots seems right to me with a Bravo 3. My 22.75' boat that weighs 1,000 lbs less, has the same transom deadrise, is overpropped with a 4-blade stainless steel prop, and my 383 before tuning does 44 knots on the GPS.

    Screeching Noise from Frankenstein 383

    This! This is the same noise mine is making. It was fixed with a 4 hole spacer and 4 hole gasket. I'm going to give it a shot for sure.

    Screeching Noise from Frankenstein 383

    Hey badrano, you may be onto something. Before you replied I may have found a lead similar to what you are saying, but am not sure. I hear what sounds like the same noise mine is making in this video at the 11:25 mark: In this guy's situation, the noise came from the Holley Sniper TBI itself...

    Screeching Noise from Frankenstein 383

    I apologize for the long story, but I will try to keep it short yet detailed. Ask questions if I need to elaborate. I assembled a custom 383 stroker engine to replace my 350 block. More details in my signature, but it has a Holley Sniper EFI and Pertronix electronic ignition set to 12* at...

    Mercruiser hesitates going to neutral

    Check your lower shift cable. Take the lower shift cable off the shift plate and gently pull it out and push it in as if it were shifting. Is it smooth and easy, or is it a little difficult?

    3.0L Mercruiser - No Power Under Load

    So it revs in the water in neutral past 3500 RPMs correct? I wouldn't rev it past 2000 RPMs on a hose unless you have great water flow. What pitch prop do you have, how many blades, and what material is your prop?

    Learning to wake board at 48. What am I doing wrong?

    That is what I suspected. You are being drug through the water. You are supposed to be pulled up out of the water when wakeboarding, which is what a tower does. With your rope so low to the water, it is not allowing you to stand up on your board. I know it doesn't seem like it should make much...

    busted bellows mounting flange

    Anything plastic so if your water tube is plastic and the little plastic or rubber grommet things that holds the trim sending wires. I was more thinking about the gasket to the transom though. You can try running cool water over the parts you want to keep cool while you weld.
