    I am getting ready to install a high speed water pickup and salt water washdown system( Groco Hi-speed strainer GRO-sth-750w) I just rebuilt my transom. I hate drilling any screws into new marine plywood, regardless of adding 5200 to the drilled holes. I could bolt the bronze pickup on some SS...

    Using Metal 2 Metal epoxy on corroded and pitted MC Bravo Transom assembly

    I am having difficulties TIG'n my corroded assemblies. These Bravos are about 25 years old and have been repeatedly exposed to salt water. Boat's transom was rotted. I replaced. I have used ss brush to remove corrosion but there maybe too much saltwater deep between aluminum molecules? My TIG is...

    Attached is photo I took of one of my Bravo 1 transom back plates. It's been cleaned up and panted gray epoxy where there was some surface corrosion. I just noticed that there is a gap of about 1/8" between end of metal ruler and surface of transom plate. It is hard to see gap on photo. The...

    Centering transom plate on Bravo 1 gimbal housing?

    I have drilled 8 holes in my new rebuilt transom. My gimbal bearing housing goes in correctly and my transom back plate fits it snug. However, I can torque backing plate clockwise and counter wise until 7/16" bolts stop movement clock or counter clockwise. The male gimbal bearing housing fits...

    Shim a MC Y-PIPE or 5200?

    I just got around examining a used y-pipe I purchased a week back. Pipe looks like it has been Fresh water used only. No corrosion at all! But, bolting surface has one lug that is not perfectly flat when bolting on transom assembly. One lower lug (not body) has about .003 gap between its surface...

    I have epoxied (2) 3/4" marine plywood pieces into place on my 270 Sea Ray AJ (dual MC I/Os) . I used turnbuckles and c clamps to secure plywood/epoxy (photo attached). Transom assembly cutouts and 8 1/2" bolt holes are all completed (not pictured.) I used outer skin holes as templets...

    Retrofitting Y pipe shutter flapper

    I just received a used MC Y pipe that was in remarkable shape until I examined shutter flappers. They are almost crap! They are of the old single round pin hinge style. The boots or exhaust bellows covered them in the photo. The shutters were in poor shape. My old y pipe shutters are in great...

    Building self-aireating live well on transom

    I am replacing my transom on a 1986 SR Amberjack. I thought about adding a live well between ODs but I am not sure that the added weight of 10-20 gals of sea water may cause transom to flex too much. I have MC v8s/Bravos and about 620 HP total. The well would have a corresponding support...

    3M Adhesive on Bravo 1 Water hose?

    It appears MC is now recommending using 3M Brand Adhesive on Bravo 1 Bellows instead of their standard bellows adhesive. Both my Bravo 1 bellhousing and gimbal housing water hose openings are slightly worn. The groves and ridges are still there but worn due to years of corrosion. It seems to me...

    How do I safely replace this Bravo 1 lube hose?

    I have MC Bravo 1s serial numbers dated at 1995 production date. They are remarkably in great shape, with very little corrosions on the outside. The inner transom plate and assemblies do have some corrosion and I will TIG to repair accordingly. Since I have both transom assemblies on my work...

    Epoxy on MC Bravo 1 Transom assembly

    I learned years ago the hard way that polyester resins will not stick well to metal auto floor boards. It will for a while but will eventually lift. I have some Bravo drive transom assemblies that have some corrosion near the bottom bolts on the inside surface. I may have lost 1/16" of aluminum...

    Bravo 1 OD bellows sealant?

    I am completely going through my Bravo ODs and transom assemblies. Bellows look to be in good shape. However former owner's mechanic seems to have applied silicon blue sealant to the male OD part that compresses against the round part of the bellows. I my opinion, he should have sanded and...

    Mercruiser Bellow Life Expectency?

    I purchased a used boat with twin MC Bravo "stroker" v8s. ODs are clean but former owner can't remember when bellows were replaced. I have one OD off boat and have inspected and found no cracks or wear marks on bellows. Boat was a trailed or stored dry and never bottom panted. Since I am also...

    Bravo 1 Water Pickup Hose kit vs. Just hose

    I just received a hose kit from GLM part number 47230. It is a kit that includes hose and adapters, barbs, etc. I am familiar with installing a Bravo 1 molded hose using an expansion driver and inserts on bell housing and gimbal ends. I am not familiar with this kit. Instructions seem simple to...

    ACX VS Marine Plywood

    It seems that I have read something concerning the usage of ACX vs Marine plywood to rebuild a transom but I cannot find it on Iboats. If anyone knows if the ACX glue is more waterproof than Marine Plywood's, please respond. Where I live, ACX is $50+ a 4x8 sheet where Marine is 70+ a sheet...

    Mercrusier Gimbal studs

    There seems to be some confusion concerning an earlier post: I cannot find any MC manual reference to the sealant used, Locktite, 5200, Permatex, etc., concerning the 8 7/16" studs used to secure the gimbal housing to a boats transom. I am rebuilding my transom and replacing many of the 8 7/16"...

    Replacing Amberjack Transom

    A couple of years ago, I purchased an older AJ, after an unscrupulous or incompetent Marine Surveyor indicated that he hadn't found any transom rot. I have replaced a Proline boat transom before. I didn't want to do it again!. However, I am now stuck with the project. Due to injuries I have...
