1999 5.7GSI PWTR
Ran fine 2 years ago. (has not run in 2 years)
Went to wake the motor up.
New plugs
New fuel filter
Had been flogged so I expected it to be a little rough getting it started up.
Engine is running very rich. Black smoke, barely idling.
- added fresh fuel to the tank
- dumped...
SEI talks about better quality components and gears than OEM on their website, and they warranty the crap out of their product.
If I was pushing 430 HP @ 5200 rpms through my drive, do you think the SEI drive would hold up better than an OEM alpha?
YES I KNOW THAT MERCRUISER ONLY RATES THEIR...
I don't know if any of you have experience with mixing and matching manifolds/risers,
But will a mercruiser riser work with a PCM manifold?
PCM engines are typically for inboards, not inboard/outboards.
Their manifolds look very much like mercruisers, and their risers bolt on in a very...

19.5' open bow
Mercruiser alpha-1 4.3 Vortec
I have no problems getting on plane, or controlling my speed.
My main concern is stability in rougher water. It seems certain waves, my boat can handle no problem, and other waves cause the boat's bow to start bouncing.

Just finished installing a shark skin electric brake kit.
Single axel, 3500#
The kit came with the back plates, all the wires, the break-away kit and the battery.
I verified that the magnets were getting power, I had someone engage the brake controller in the truck, and the magnets attracted...
I was trying to answer a question for fabrimicator the other day, and it got me thinking.
We all know running too hot of a cam can cause water to enter the combustion chamber through the exhaust.
And we all know manifold riser extensions help keep water out of the manifolds in situations where...
Finished a day of boating, went to rinse the leg out, and noticed some damage to my lower drive.
I have absolutely no idea how it happened. I Don't recall anything coming close to the drive, and I certainly don't remember hitting anything.
I was beached for awhile, but my leg was lifted, and...
All my local suppliers are useless.
I'm looking for a salt water friendly electric brake kit for my trailer.
#3500 axle, need the backing plates, shoes, and all the hardware.
I've been calling around local trailer shops to find an electric brake setup for my trailer.
I just had a long conversion with a technician who told me that electric brakes have no business being on boat trailers because of corrosion. He said that even in fresh water, they would only last a...

2 year old controls (throttle/gear)
When cruising (1/4 - 3/4 throttle, 2000 - 4200 rpms or so), the engine seams to randomly loose, then gain power.
I haven't had a chance to take anything apart yet, as my tools are in storage (moving). but this is what I know so far...
I know you 383 guys like to up your compression, run a hotter cam, and rev your motors up to 5500 rpms (or higher), but I'm wondering if anyone has tried to get more power by increasing flow, rather than compression and rpms.

I've got a late 80's Regal Medallion 195.
I've stripped the interior, and started rebuilding everything from scratch (side pieces, engine cover, console, glove box, etc)
I removed the factory carpet, and now I just have the plywood/fiberglass deck.
I want to re-do the floor now, but I can't...
Controls (throttle / gears / trim) part number: 827270a43
I'm doing some interior work in my boat, and I need to remove the controls from a piece of plywood so I can install it on the new plywood.
I tried putting the throttle at 1/2 in fwd and removing a small allen key, but that didn't seam...
Alpha 1 - MR
Last year I Changed a bunch of stuff, including my shift cable and bellows.
Since then my reverse has never engaged properly. It either grinds, or hits shift intterupt (and stalls the motor).
Now, I don't remember all the details of installing the new cable, but I remember I was...
