    4.3 Mercruiser 4 BBL Intake Options

    Hey guys - We've been enjoying our 1996 SeaRay 175 project for a few seasons with the older 4.3 2 bbl. that the previous owner installed. That install came with some "creative engineering" in wiring, shimming pullies for belt alignment and more.....We've really enjoyed boating so I'm going to...

    Under Propped now Over Propped

    Absolutely sticking with his recommendation. I was just wondering if anyone had the same combo and how they like it. BTW, Ken was fantastic. Very helpful.

    Under Propped now Over Propped

    Thanks for the referral. He recommended a PTZ3: 14.25 x 20, PTZ320P. Unfortunately there is a several week delay/back order. On the quest for a used one. Anyone else with my boat running that prop? How do you like it?

    Under Propped now Over Propped

    Hey all, I'll start with the standard disclaimer that I did a lot of reading and searching to try to find my answer but not sure I'm gaining any better understanding. Finally got the Sea Ray 175 4.3L on the water and it was a slug. Took forever to plane and top end was 36-38 mph with GPS...

    Fuel Delivery Issue

    Same issues on my second time out. Starved for fuel even after replacing the fuel hose. A good look in the tank and there is a fair bit of rust chunks around the pick up tube the hat appeared to be plugging it. Removed the tank, flushed it and so far, no more issues and seems to be...

    Hole Drilled in Bilge Tank - By Design?

    Sealed up the holes temporarily with a marine silicone. Had it out twice for 5-6 hours each time. Cleaned the sealer out of the hole and no water came out. I really think the 7 gallons was from my first trip on the water. Doesn’t seem there is any water intrusion so permanent fix in the...

    Hole Drilled in Bilge Tank - By Design?

    Did a little looking today. The hole on the right side appears to be from someone (before me) over drilling a hole to mount the battery tray. I blew air into the hole and absolutely no water came out, and it pressurized very quickly so suspect the area inside the void is likely not damaged...

    Hole Drilled in Bilge Tank - By Design?

    I wondered about someone trying to drain water too. I think both would be accessible through the engine compartment. The left side hole goes into the motor mount pad and the one on the right is just forward of the trim pump assembly. Neither are seen on the inside. Good idea of cutting the...

    Hole Drilled in Bilge Tank - By Design?

    I’ve owned it for a year and bought it as a project. 1996 175 model. Last registered in 1998 so been off the water for 22 years. From what I can gather, it wasn’t winterized correctly, cracked the block so there it sat. I’ve had it out one time since getting it running. That was this past...

    Hole Drilled in Bilge Tank - By Design?

    Yes, both are below the water line. So I suppose there may be a bunch of water inside the hull that is not accessible through the inside or outside of the boat?

    Fuel Delivery Issue

    On my maiden voyage yesterday, we were cruising at about 4000 RPM. Boat lost power and killed. Quick diagnosis discovered that I was not getting fuel from the tank to the water separator/filter. I removed the ASV and it moved freely and allowed me to blow air outward. It took a little lip...

    Hole Drilled in Bilge Tank - By Design?

    Got looking a little closer and pushed a pick tool into the hole. I can't see it in the bilge are. Had someone move the tool around and it sounds like it is within the engine mount base in the engine compartment. Ironically, I looked at the other side again to see if there was another, and...

    Hole Drilled in Bilge Tank - By Design?

    Very odd...why the heck would someone drill a hole there? Just glad it isn't a gaping hole. Regardless, any recommendations on repairing it without having to do a bunch of body work or having to take it to a shop? I've had positive results with JB Weld for many other repairs but have never...

    Hole Drilled in Bilge Tank - By Design?

    Noticed a 1/4 or so hole in the bottom of my boat. It isn't caused by damage, it is a perfectly drilled hole. Its on the lower left side of the boat. Is this by design and if so, why?

    1996 Seay RAy 175 Serious Electrical Issues

    Circling back to close this thread with the cause. Turns out the guy I got it from wired the alternator incorrectly so when I installed a new alternator, so did I. The ground wire was connected where the orange output lead was supposed to be connected. As a result, power ran through my ground...

    1996 Seay RAy 175 Serious Electrical Issues

    I verified the positive side circuits and all is working as outlined above....except the ground on the slave. It has the 4.x ohms of resistance. Doesn't crank. I jumper a ground from the slave stud to the battery negative and it cranks. So, bad ground. I jumper cabled from a clean bolt on...

    1996 Seay RAy 175 Serious Electrical Issues

    I verified the ground cable had a clean tight connection between the battery and block so should be covered there. I’ll be digging in this weekend to verify the primary engine circuits to see if I can get it to fire up.

    1996 Seay RAy 175 Serious Electrical Issues

    Thanks for the information guys. Appreciate the insight and comments. The two stray black wires traced back to the junction in the center of the diagram so I'm certain they are grounds. The 4 ohms of resistance is happening on the exiting side of the cannon, terminal 1. I traced every...

    1996 Seay RAy 175 Serious Electrical Issues

    Man...54 views and nothing? Can anyone tell me if the Mercruiser Shop Manual has all inclusive wiring diagrams? And if so, what version (I've seen #18 and #25) I need for my boat? Or what about the Clymer/Haynes manuals? They say complete electrical schematics but has anyone used one one...
