I still can't figure out why the edelbrock marine carbs don't have at least a PCV vacuum port. I would think marine engines would especially want a pcv installed. The air cutouts are all there! Here is how to fix the problem easy as 1 2 3!
1. With a 1/4" bit, drill from the bottom upwards until...
Right about 60mph it sounded like my prop started to aerate, rpm spiked a little and all at the same time the stern of my boat started sliding out to the side. I immediately pulled back on the throttle and came right out of it. Water was smooth, I wasn't near peak rpm. 26" prop. Measured by gps.
My front anchor tie or dock cleat screws are loose. They have a nut on the back side of the screw. I assumed there would be an access hole behind the most forward back rest. Being since the rest of the bow is currently being reupholstered, I pulled the small pad off. I was shocked to find the...
What is a GIL exhaust manifold? Including a picture. Will these provide better flow for a built engine? Rather than having a water hose top and bottom, it has a loop on the top and only 1 water line hooks to the bottom of the manifold. They have a y-pipe (not pictured) to hook the 2 water lines...
Pulling the 220 horse 5.0 and dropping in a fresh 383. I'll be conservative and say it will put out 400 horse.
Right now it will do 50mph easy on a 21" prop. 55 by myself. GPS clocked.
I have a few props to try with the new engine up to 26". So how much of a gain in top speed can I expect? To...
I have a mercury outboard 50 horse. Had it checked out once my local boat mechanic said hes pretty sure it has a 75 horse power head somebody had swapped at some point. Not sure if this is possible? I know it pushes my 16 foot polar Kraft about 35 it screams for a John boat being steering...
Paid for next day air. Planning a long boating trip with the family saturday. Stern heavy boat rides so rough. Was so excited to get the tabs on. The box was seriously missing a complete actuator. So not happy. Bought from amazon
Clicks or knocks softly in neutral trimmed clear up.
Vibration felt and audible hum when on plane and turning left or right, same reaction trimmed clear down or up on plane. There is a happy window with no noise or vibration on plane just above from trimmed clear down. Problem has gradually...
I have a 93 rinker captiva 186. It's 2500 pounds give or take dry. 18ft. Largest engine from rinker was 4.3 but is fitted with a 5.0/lx. I thinknow rated at 230 horse.
It currently tops at 55gps and still feels really stable. I'm having a serious thought of swapping it with a 350 mag mpi 300...
23 foot pontoon, mercruiser 3.0. 21 pitch Mirage prop. 35mph wot light load tach reads 2200 rpm. That would give me -67% prop slip.
Realistically I'm turning 4600 rpm or so.
Boat was bought brand new 4 years ago by my parenents. All this time he thought wot was 2200 rpm.
What's the deal?
18' rinker captiva approx 2500 pounds dry empty. 4.3 was the largest engine offered but it's been fitted with a 5.0/LX. Alpha one gen 2, 1.83 ratio drive.
A 21" prop puts me 400 rpm over engine max which is 4800. Local marine shop says with my setup I can easily handle even a 28" but no way to...
Basics first. 1993 rinker captiva 186. Original 4.3 now has 5.0/lx. Sticker is missing from out drive that gives ratio. I only have the serial number 0F053311 which tells me it is an alpha 1 gen 2.
I have ran 2 props both stainless both 21" pitch.
