I haven't been able to find where to drain the coolant out for a drain and fresh refill. Lots of info out there on the seawater side, but not much on the closed coolant side. Mercruiser 5.7 MAG Horizon inboard.

I've seen some rumors that someone made an extension for the v-berth but my searches turn up nada. Anyone know where a post on this might be?

Last year my depth reading were all over the place, and I would get a high seawater temp notice. I believe both of these readings come off the same transducer. The boat hasn't been launched yet so I'd like to take care of this while its on the hard. Any tips for figuring out if its a...

I have a false high sea temp error and also depth issues so I'm guessing there's an issue with the transducer or wiring. Which of these 2 should I be looking at to repair or replace and what is the other one? Cleaning the bilge is also on the list...

I just installed a new (polymer) cutlass bearing, went fine, definitely a pain in the ass to get the old one out and press the new one in. I started putting the shaft back in and can only get it about a foot in before it gets so tight I can't push it any more and it's extremely hard to twist...

Does this Kicker amp pair well with these JL speakers and sub? Will it be powerful enough for cockpit only? Just want it to be loud enough while underway and sound good and clear at medium volume while on the hook or mooring. Kicker KMA600.4 Multi-Channel Marine Amplifier Qty 4 JL M3-650X-C-Gw...

I think there should be a knob or 2 to stop it from sliding. The holes on either side of the latch that converts it from a back-to-back seat to a lay down lounger don't have threads. What am I missing? This pic shows the latch and one of the holes to the left of it

Looking for a part number for the coupler for the shaft to the transmission for my 2005 Amberjack 290 with V-drives. Where can I find this information? Better yet, where can I buy one?

I can't figure out how to operate my windlass. Here's a pic of the controls: And a video. The windlass isn't moving but you can hear a click when I press up or down on the MAIN switch: https://www.youtube.com/shorts/hO-XhXVM19k

The left hand instrument gauge for my port engine isn't working. All needles for oil pressure, engine temp, fuel and voltage read zero while underway. How should I try to repair?

I'm thinking about adding some brackets in both aft corners for a pelican case for tools on one side and a second anchor in the other corner. What are the best practices for screwing into or otherwise fastening stuff to the bottom/bulkheads/side of a bilge? I want to be careful that I'm not...

I'm changing out the alternators, belts and raw water pump impellers. Due to v-drives, access is TOUGH on these, reverse mounted 350 mag mpi horizons! While I'm crammed in here wondering what else I should do before I put everything back together? This part near the bottom looks pretty rusted...

Hi All! I have a swinging door on my transom to get to the swim platform; I assume it's similar on most Searay sport cruisers. Is there a latch or clip on any models that hold the door open? I want to install something this spring. I'm sure I could use a bungee cord, or door stop or something...

I'm having trouble finding info based on my engine serial number, its a 350 MAG MPI Horizon (V-Drive inboard) on a 290 Amberjack The serial number is OM396504. On more than one website I'm finding it listed as a 6.2L, but I'm pretty sure it's 5.7. Am I looking this up correctly...

I need to replace the alternator on the port engine and will probably just do the starboard side at the same time. What brand should I go for? Several options on amazon... Mercruiser 350 MAG MPI

I might have lost my keys...both ignition keys and the cabin door. If I can't find them what do I do?

This is a pic of one of my 2 props (Amberjack 290 w/ inboards). Is this something I should get repaired, or not worth the trouble/expense for such small damage?

Getting things ready to haul out this week. Should I remove the canvas before they haul? I plan to remove it eventually to have some repairs done and will be shrink-wrapping, but in the meantime I want to keep the canvas on to protect the cockpit if it's practical. Anything else I should do...
