    Thinking about converting surge brakes to electric - Tri-Axle Trailer

    That is what I was thinking that the brakes are not fully engaging. If I were to go electric over Hydraulic, I'd want to make sure it had enough power/volume for 6 disc brakes.

    2000 Sea Ray 190 CC Hull Soft Spot

    The hull is about 8-10mm thick in that area. Often the strakes have an extra layer of glass than the surrounding areas.

    Thinking about converting surge brakes to electric - Tri-Axle Trailer

    Yes, it might just be wet brakes or sticky calipers . . . I don't drive the rig often or far enough to really exercise the brakes. I took the trailer out on the road to test the brakes, as per my other trailer thread, and they are working . . . just not sure they are working well enough. It...

    Thinking about converting surge brakes to electric - Tri-Axle Trailer

    My 2021 trailer came with surge brakes on all 6 wheels. Even so, stopping is a weak-point as it puts too much forward pressure on the truck. I'm assuming that with electric/hydraulic brakes the trailer will tend to stop more on its own. I am thinking about a conversion to electric (what I...

    Fiberglass resin question

    Don't tell anybody, but I use exterior grade plywood instead of marine grade. It is pretty much the same, the veneers are just not quite as good at marine grade. Same permanent adhesive. 'Greenwood XL' and 'Perma Panel' are a couple brands of the rot-resistant plywood that boat manufacturers use.

    2000 Sea Ray 190 CC Hull Soft Spot

    No coring, no foam, etc. Right? It is a little hard to tell from the pictures, but it looks like the cracked area may be a void (air pocket) in the lifting strake (the same area that shows the clipped gelcoat on the outside of the hull). This would most likely be a manufacturing defect when...

    2000 Sea Ray 190 CC Hull Soft Spot

    Also . . . Has this boat been in an area where temperatures get below freezing . . . 0˚ C ? (I know the OP is in New Zealand) If a cuddy compartment had a significant amount of water in it at some point and was allowed to freeze it would create an outward bulge in the hull and possibly lead...

    2000 Sea Ray 190 CC Hull Soft Spot

    Sorry for the multiple posts, but . . . Here is a picture of your boat (same boat). You need to look in the storage compartment after having removed the cushions and see what the inside of the hull looks like in the area of question. . . Post some pictures of that area, if you can.

    2000 Sea Ray 190 CC Hull Soft Spot

    Here is a Sea Ray factory video that shows how the boats are made. It is from a slightly newer era than your boat, but their methods look traditional. At one point they talk about coring in the cockpit/deck mold, and they state there is no coring in the hulls. Here are a couple of photos...

    Freshwater Boat to Saltwater

    Outboards do not (should not) live in the water, so it may not be surprising that you would not find aluminum anodes for it. If you can get Zinc, then fine. Just don't use magnesium. Be sure to tilt the outboard up out of the water when not in use. Sterndrive boats that live in the salt...

    2000 Sea Ray 190 CC Hull Soft Spot

    No, I doubt that you will find any coring material under the fiberglass. I would not drill into the area either. It looks to be from an impact or over stress in that area. Do your investigation from the inside of the boat (i.e. the cuddy cabin) and remove cushions, open storage areas until...

    Check those wheel bearings . . .

    I got a couple of grease tubes and proceeded to pump the other axles with more grease. Looks like I’ll be replacing bearings on 2 wheels, not just one. The original grease Zerks are the pressed-in type and one of them came off with the grease gun. I’m thinking that I should replace them all...

    No compression with rocker arms torqued

    Rocker arm noise. . .Usually it is after the engine is all buttoned up. Not sure what the spec is for the adjustable valves, the Mark IV engines were 1/2-1 full turn IIRC. 1/4 turn seems light. Maybe get everything adjusted and then run the engine for a while to be sure.

    No compression with rocker arms torqued

    Glad you found the issue. The Gen 5 454's were not fan favorites because of the valve train. Now with the conversion kit you should be good to go. Just make sure 1/4 turn beyond 0 lash is enough.

    Fiberglass resin question

    Polyester resin often has wax mixed in to provide a barrier to air while the resin cures. The wax 'floats' to the surface of the resin after application providing the barrier. It sounds like that is what you are referring to(?) The are resins that don't have wax mixed in are typically used...
