2007 GW Marlin looks like the ProMariner charger is dead. I have my batteries set up this way: 1 starting battery for each engine, isolated from two batteries that are my "house bank" that are charged by any excess voltage from the starters. So functionally three batteries. It has worked...

My interior lighting fixtures on the 07 Marlin are getting old and showing their age. What have y'all replaced them with? I've already swapped the dome light with an LED replacement... this light would work for the head overhead light as well when it is time. How about the swivel base gold...

I"m away from my boat for about 3 weeks, I'd like to put a storage box on the bow of my 2007 300 Marlin in the walkaround space just aft of the windlass... unfortunately the measurement I took before I left the boat has evaporated and my old mind can't remember if it was 15 or 17 inches wide box...

Skipping the long story, anyone put a dedicated towing eye on their Marlin? How, where, what? I don't see how to do it easily with the windlass being on the centerline. I'm wondering if two eyes adjacent to the windlass (backing plates etc..) and a bridle is the way to go? 1- No, I'm not...

Repowered my 2007 30' Marlin with 2022 300 Verado's V-8 after 15 years of use on the Yamaha 250's. Ken at PropGods sold me some Q4 (similar to the Rev4 Merc) for the old motors which worked great on the 250's for hole shot and stern lift, and Ken said give them a try on the 300's first. These...

I need a replacement for my starboard wiper motor. I'm away from the boat for next two weeks and my dealer says the one I ordered in the past is discontinued, with no exact match suggested. I thought I'd try to source myself. Anyone have the part number or have replaced theirs recently with...

I'm moving the boat to Alaska this spring and was considering my weather data and communication options. I think I've settled on SAT phone for emergencies and clearing customs via NEXUS if they let me... but the weather data through PredictWind and real time buoy reports sounds intriguing via...

Thinking of buying a cover for my cockpit after I get this SeaDek project completed. Mostly for bird dropping protection/UV, but also for rain displacement overboard. Anyone have any experience with this? Is there a manufacturer that has one specific for the 300 Marlin or do I have to go custom?

Trying to pick a color for my cockpit etc... I'm horrible at colors. I'd like to see some of your samples! Thanks! Randy

Repowering my ‘07 300 Marlin this winter. I’ve decided on 300 Mercs. The Verado is recommended by the dealer and mechanic, but the SeaPro is the same block de-tuned, has more stainless below the waterline, and a bigger alternator (my Raymarine electronics and fridge burn through my battery...

Had a crewmember zig when he should have zagged and cracked the fold down part of the slide back smoked acrylic hatch to the cockpit on my 2007 300 Marlin. Can someone throw me a bone as to the best option for replacement? I've done some initial searching without success and my next call...

I’ve been replacing the blades on my wipers pretty well the past few years, but today I notice the wiper arm on starboard is bent a bit and showing corrosion. I’ve never liked these cheap wipers on such a nice boat, and have often wondered if anyone has upgraded the entire assembly with...

Thought I’d start here late tonight before calling GW service tomorrow, but my dome light at the helm just crapped out. The switch for courtesy light is funky. Can still turn on floods. Looking for a new full unit probably, can you steer me in the right direction?

I'm kindof sick of the amount of maintenance and babying I have to do for my 2007 FP Mini4+ generator. For a handful of reasons this thing requires the capsule to be removed WAY TOO OFTEN to replace relays, troubleshoot, etc... Not to mention how I have to dislocate my shoulder to access the...

Hi fellas, It was a sad weekend with one of my 2007 Yamaha 250's breaking a rod, we can discuss particulars of the situation in another thread or PM, so if we could stick to topic here I'd like to hear individual opinions on repowering the 2007 era Marlin. I'm not 100% sure I'm going re-power...

My 2007 Marlin has a porthole window facing aft that has broken latches. Instead of simply caulking it in the shut position (which I may indeed do as time is running short for pre-trip projects) I have been looking for a full replacement. I haven't called GW yet since I don't want to pay the...

I’m reconfiguring my battery supply. Two starting batteries one for Port one for starboard and a house bank too. I’m confident of all the hookups in the battery compartment, and would lik to assure from another source what exactly the batteries ground TO? Basically what’s the...

Hi fellas, Redoing battery config finally. Setup will be two isolated group 24's, one for each engine, starter and alternator, there will be nothing else attached except one bilge pump per. I am replacing the two group 27's with new as a true house bank where everything else will draw...

My Icom VHF just crapped out. On/off button, and I've been having some transmission/recieving questions recently anyway. Time for a new one. Since I have a recent Raymarine install with Lighthouse III and Axiom on my MFD's which have AIS transmission, I was considering adding a receiver...

This is a can of worms that I don't want to feel bad dragging you guys into, so I think I can get my answer if I just ask one question to Marlin 300 owners from my era (2007) who have a diesel tank installed in the aft bilge that supplies their Mini4+ Fischer Panda Generator: Here's the...
