    Sizing a Bravo 2 prop

    I have a situation here that I hope you guys might be able to help me sort out. I lost my Bravo 3 last summer to a submerged log. The outer prop broke loose with the shaft attached and the drive ran on saltwater instead of oil, so it is toast. The drive was 2.0 ration with 24P dual props...

    ​Bravo 2 to temporarily replace Bravo 3

    Gentlemen, I lost my Bravo 3 last summer to a submerged log. My plan is to rebuild my 454 and get a new Bravo 3X. However, I have a Bravo 2 with the same ratio (2.00) in my garage that I bought for my other boat to replace the Alpha. Can I run my 2855 on that Bravo 2 for a summer or two...

    Bravo 3 outer prop is gone along with the shaft. How can this happen?

    When I was checking the engine this morning in preparation to head out for kings, I noticed the outdrive oil reservoir is bloated. I unscrewed the cap and pressurized oil hissed out. I did not take this lightly and decided to cancel the trip and head back to my home marina 20 miles away. Midway...

    I have 7.4 + Bravo 3 with TB ignition. I want to replace my coil or at least carry a spare with me. I read very good reviews on the Flame-Thrower and I also read that it used to be recommended here on the forum all the time. I can find replacement part numbers for different makes but not the...

    When ignition systems break, do they die or malfunction?

    I read some threads in which the boat owner complains about erratic behavior at certain RPM and it turns out that it is the ignition system and by changing it, everything is back to normal. With the way distributor based electronic ignition systems are constructed, if the break, I would expect...

    Composites transoms, why not 100% fiberglass?

    We been debating the subject of wood cores on this forum for very long time. We also discussed the Seacast route and I believe we all agree that Seacast would have been our first choice if it wasn’t so expensive and requires a dam to be fabricated sometimes. Recently, I have been thinking...

    Experts, please advise, old or relatively recent blocks are preferable?

    I am building a 350 out of a cracked 305. Found a candidate block with casting number 3970010. References say it is 69-79 block. Seller says it has 10% more nickel which makes it high performance candidate, I searched all over for definitive opinion in this but it seems to be one of these...

    Roller cams and vortec heads, can they be added to any block?

    We (myself and few friends) having a conversation about engines and one said that the engine MUST be vortec originally (>=1996 vortec engine) to be able to install vortec heads on it. Also, the same person said that roller cams CAN'T be used with an engine that had flat tappet cam originally. I...

    Which Camshaft?

    Hi iBoaters, My 1996 7.4L has a roller cam. I looked up the cam on MercruiserParts and it is about $600. I know this is the marine “thing” talking. Different RV profile cams online are way below that by almost a half. Where can I find the actual parameters of the installed cam so I...

    Check your safety gear

    Last weekend, I took my son fishing in Puget Sound, WA. We had channel 16 on all the time. In about 4 hours we listened to 1 boat taking water very close to us and 2 boats on fire near San Juan islands. It was crazy. Everett PD marine unit asked the captain of the boat that is taking water to...

    Do we need to vacuum test Mercruiser outdrives?

    There are conflicting info on the vac test (I am not referring to the pressure test but rather the Vac test). Some say this test was never meant for Merc and it was only recommended for OMC drives. Some also say it actually has the potential of damaging the seals of Merc outdrives. Where is...
