I am helping a friend do some winter work on his boat a 38' Jefferson Yachts with a Simpson Lawrence Sprint 1000 (since acquired by Lewmar) anchor windlass. The windlass manual says the working load is 60 amps and manual recommends 1 AWG or 1/0 depending on the length of the run (71' or 89'...

Yesterday at the local raft up place, a 30 or so foot newer Sea Ray open bow boat with 7 or so people on it is idling through the anchored boats looking for a place to anchor. They are about 30 feet from us, and i see two kids on a tube being towed behind the boat. They have 4 or 5 feet or so...

Installing a new Cool Fuel 2 FPR in my 1998 370 DA with 454 MAG MPI Horizon Engines (S/N 0L006007). Merc Part Number 860349A1. The FPR does not come with the gas line connector, and that is a separate part (Merc Part Number 22-808002A1). This part looks to be a 1/16" MPT pipe nipple by 45...

Saw these 4 in formation on the Niagara River yesterday. Anyone know who and what they are? I'm thinking military.

My Standard Horizon CP180i screen has taken a turn for the worse. The screen is no longer sharp and is getting worse. It is not worth repairing IMO. I am looking for a replacement GPS chartplotter with navigation maps and built in GPS antenna. I do not need or want sonar or another depth...

Anyone know exactly what the difference is between a set of Mercruiser Blue Plug wires (84-7701A17) and Mercruiser Red Plug wires (81-6608A68). Both these are 454/7.4 Merc big block wires. My boat which is a 7.4 Mag MPI Horizon (SN: 0L006006) apparently calls for the Blue Wires, but i have...

I just received my oil analysis reports and Blackstone Labs suspects I have coolant showing up in the oil. Engines are Mercruiser, 7.4 liter MAG MPI Horizon 380 HP w/ Velvet Drives with closed cooling. The boat is a 370 DA used in freshwater its entire life and has 700 hours on each engine...

My RayData unit (depth, speed, temp) is becoming increasingly hard to read as LED pixels go blank, never to be seen again. If anyone who has upgraded their electronics has one of these available they would like to sell for a reasonable price please let me know. Thanks JohnG

I was asked by a dock neighbor to look at a 2000 340 Sundancer that he is considering purchasing. The boat has twin 7.4 liter raw water cooled I/O s with Alpha 2 out drives. In the ER, there are the usual SeaRay stringers (grey gelcoated about 1.5" wide), BUT on each side of each of the 4...

Question regarding propeller reconditioning on a 370DA with 7.4 MPI Horizons (380 HP). Props are OEM i believe (18 by 22 1.5" shaft Nibral). Boat is new to me last year. Ran it all last season and no issues with props that i am aware of (no vibration, RPMs good). One prop looks like PO did...

Looking at a Westerbeke 7.0 BCG in a 1998 370 and have a question. I ran it today to check it out. It could not run 2 AC units and the hot water heater but could run 2 AC units without the hot water heater. I assme the load was too great for everything at once. My question though is with the...

On my 1990 310 EC the instrument panel dimmer knob (rotary knob) no longer works. Panel lights are full on all the time. It used to work, but one of the panel illumination lights (starboard voltmeter) got shorted out due to a loose connection on the back of the instrument. At the time i kept...
