    I think I've found a hull for my project, it's a 77 Renken 19' bowrider that has a fairly good hull. The boat was slipped at the lake and has algae growth and (quagga?) mussels on the hull and drive, but I'm not sure if this is a deal breaker. Here's a few pic's There's a lot of algae and...

    What's your Mercruiser 3.0 in?

    What type of hull (style, length, year, manufacturer) do you guys have powered by a Mercruiser 3.0 (140/135HP) I'm looking for another hull to replace my 73 16.5' SeaSwirl tri-hull. I'm thinking of a 17-19' V-hull bowrider, but don't know if a 19' hull is going to be too much for a 140HP...

    Wet foam weight, 73 16.5' SeaSwirl

    How much weight will wet foam add to a 73 16.5' SeaSwirl tri-hull? (After an hour of looking at old posts for an hour I didn't find the answer.) I know water is about 8#/gallon, but don't know how much foam is in the hull for a guesstimate of the extra weight. The floor was bad years ago and...

    I found another problem during my engine install ... (72 Mercruiser 140HP 3.0 S/N 2913009, #1 drive S/N 2901044) I removed the exhaust down pipe (so I could remove/replace trim hoses) and noticed there was no gasket used between the gimble housing and exhaust down pipe :eek: I assume there is...

    Mercruiser #1 trim limit switch?

    I found the insulation of the trim limit switch wires is hard/cracking and missing in places, so I need to find out how to replace the switch. After looking around for online manuals I didn't find any of them that referenced this old style switch on my 72 #1 drive (S/N 2901044). Here's a shot of...

    72 Mercruiser #1 gimble bearing service life

    I replaced the gimble bearing on my 72 Mercruiser 1 drive (S/N 2913009) while replacing the bellows 2 years ago. After the job was finished, I found out that the carrier should have been installed backwards so the bearing could be flipped 90 degrees and removed from the carrier for greasing...

    Mercruiser 3.0L rocker arms

    Hi all, I need to order a set of 1.75:1 ratio rocker arms, balls and nuts for my 72 Mercruiser 140HP (3.0L 181CI) engine, noticed a few of them galled up during engine rebuild. Marine dealers want over $100 for the set, but from what I've found GM inline 6 engines use 1.75:1 3/8" rocker arm...

    73 Mercruiser 3.0 engine, rebuild or swap, compatible years?

    I have a 72 SeaSwirl with a bad Mercruiser 3.0L engine and trying to decide if I should rebuild or replace it with a complete late model 3.0L. I haven't been into the engine yet, but it sounds like it threw/broke a rod, clunk/knocking noise coming from the bottom of the engine. I was idling and...
