The Bilge Files — 7 Guides the Marine Industry Hopes You Never Read

What you get

Seven guides that do the homework the seller won't.

Each one is built from physical teardowns and mechanic interviews — with exact part numbers, real dollar amounts, and the opinions a sponsored channel can't print. Here's everything inside the file.

The Pre-Purchase Inspection Checklist

47 points in the exact order to check them — transom tap-tests, compression readings, moisture targets, wiring red flags, and the seller behaviors that predict hidden damage. Printable tear-out included.

The $50-Fix Bible

15 repairs shops charge $300–$800 for, each under $50 in your driveway. Impellers, thermostats, steering cables, trailer bearings — with part numbers, tools, and step-by-step instructions.

The Marine Electronics Survival Guide

How planned obsolescence really works, transducer cross-compatibility, valuing used electronics in a negotiation, and the independent repair sources manufacturers pretend don't exist.

The Outboard Blacklist & Buy List — 2026

Engines ranked by what I found inside them, not the brochure. Brand-by-brand BUY / CONDITIONAL / AVOID verdicts, HP sweet spots, and the used-buying red flags by brand.

The Dealer Decoded Playbook

How markups and holdbacks actually work, how a $35k boat becomes $78k through financing, what "certified pre-owned" really means — plus word-for-word negotiation scripts.

The Hull & Build Quality Rankings

Boats graded on 7 criteria from physical teardowns — stringers, transom builds, wiring, hardware — in a 4-tier system from "built to last 30 years" to "designed to fail in 5."

The Fish Finder Field Guide

How to choose a unit, set it up, and actually read what it's showing you — sonar and CHIRP, the four imaging types, transducer mounting, and reading arches, bait, bottom hardness, and the thermocline. The screen isn't lying; you just haven't been taught to read it.

The read-back

Learn to read the listing back to them.

The whole approach in miniature: every confident phrase in a boat ad has a quieter truth underneath. A few you'll learn to decode on sight.

The listing says…

What it actually means

"Bristol condition"

A seller's adjective, not a standard. It means "I think it looks clean" — check the transom and stringers yourself.

"Freshwater only"

Usually unverifiable, and often untrue. Corrosion hides in the same places regardless — the guide shows where to look.

"Just serviced"

Frequently a receipt for an oil change — rarely the impeller, gearcase, or thermostat. Ask exactly what was done, and for the invoice.

"Runs great"

On the trailer, in the driveway, for ninety seconds. Means little until it's run under load with a compression test on every cylinder.

"Low hours"

Hours can be reset — or genuinely low because it sat for years, which is its own kind of damage to seals and fuel systems.

☐Tap-test the transom with a dead-blow hammer — a dull thud means water in the core.
☐Drain a lower-unit oil sample onto a white rag. Milky gray = water past the seals.
☐Compression-test every cylinder. Any reading 15%+ low = an internal problem.

The math

What guessing costs — and what knowing costs.

The dealer lot and the repair bay are expensive places to get it wrong. These are the typical real-world ranges the files are built to help you avoid — set against what the files themselves cost.

If you guess typical exposure

A bad boat purchase you couldn't see coming$10,000–30,000

Paying a shop for repairs you could do yourself$3,000–7,000

Financing markup, hidden fees & trade-in undervaluation$5,000–20,000

Electronics obsolescence over five years$8,000–15,000

Exposure to one or two bad calls$10,000+

If you read the files one-time

All seven guides — 172 pages, part numbers, scripts & checklists$39.99 $19.99

$39.99 $19.99

Avoid a single soft transom or financing trap and it pays for itself hundreds of times over.

Figures are typical real-world ranges drawn from the guides' own teardowns and interviews — illustrative, not a guarantee. Your actual numbers depend on the boat, the seller, and the choices you make.

What buyers say

Bought before a boat. Paid for itself on day one.

★★★★★

"Used the 47-point checklist on a 2019 center console the seller swore was perfect. Moisture meter hit 22% on the transom. Walked away from a $35,000 mistake in ten minutes."

Greg M. · verified buyer

★★★★★

"The dealer playbook alone saved me thousands. Walked in with credit-union pre-approval and negotiated out-the-door. The finance manager's face when I declined the warranty was priceless."

Tom R. · verified buyer

★★★★★

"Did my own impeller swap in 25 minutes with the exact kit the guide lists. Shop quoted me $650. Total cost: $18. The $50-Fix Bible paid for the whole vault on fix #1."

Dave K. · verified buyer

★★★★★

"Ran the compression test on a boat I was about to buy — cylinder 3 was 40 PSI low. Seller had no explanation. That $15 tester just saved me from a powerhead rebuild."

Rick P. · verified buyer

★★★★★

"No idea dealers mark up the lender rate and pocket the spread. Switched to my credit union and saved over $6,000 on a 15-year loan. One chapter changed the whole deal."

Mark S. · verified buyer

★★★★★

"Repacked the trailer bearings and replaced the wiring harness myself in an afternoon. Exact part numbers and tool lists. My mechanic buddy said I did it cleaner than most shops."

Jim W. · verified buyer

Is this for you?

Built for one specific reader.

This is for you if…

You're buying your first boat and don't want to hand $40,000 to someone hiding a soft transom under fresh gelcoat.
You already own a boat and you're tired of $650 bills for an $18 impeller swap.
You're walking into a dealer this season and want to know how markups and financing really work before you sit down.
You'd rather understand the purchase than trust a five-star listing.

This is not for you if…

You want a single "just buy this one" answer with no reasoning.
You're a marine surveyor who already does this for a living.
You're after the cheapest possible boat regardless of what's wrong with it.
You'd rather not know what the teardown shows.

From the author

Why I wrote this.

I'm Cole Beckett — the guy behind Hull Honest. I tear boats apart on camera so you can see what's inside before you spend a dime. No brand deals, no dealer partnerships, no sponsored reviews. Every engine I cut open and every hull I split in half, I paid for myself, and I say exactly what I find.

After 28+ teardowns I had a hard drive full of part numbers, dollar amounts, and verdicts that never fit in a ten-minute video. So I organized all of it into six reference-grade guides — the ones the marine industry would rather I kept to myself. The goal is simple: to leave you harder to fool than the day before you read them.

Before you buy

Questions people ask first.

What do I get exactly?

Seven PDF guides delivered instantly after purchase — 172 pages total. Read them on any device, print them, and take them to the dealer lot, the shop, or the boat ramp. They're yours forever.

Is this just your YouTube videos repackaged?

No. The videos show individual teardowns. The Bilge Files compiles months of research into organized, reference-grade guides with specific part numbers, dollar amounts, checklists, negotiation scripts, and brand rankings that don't fit in a ten-minute video.

I'm buying my first boat. Is this for me?

Especially for you. Guide #1 — the 47-point inspection — can save you from a five-figure mistake before you spend a dime, and Guide #5 has word-for-word scripts that take thousands off the purchase. This is the one you read before you buy.

I already own a boat. Is there still value?

Yes. Guide #2 covers 15 DIY repairs that save $3,000–$7,000 in shop fees, Guide #3 helps you beat the electronics obsolescence trap, and Guide #4 tells you what your engine is really worth. If you own a boat, you're already spending money these guides can save.

Do you take sponsorship money from any brands?

No. Not on the channel, not in the guides, not ever. That's the entire point. Every opinion is mine, informed by teardowns, mechanic interviews, and community feedback — and it's clearly labeled as opinion. Nobody paid for a favorable review.

How do I get it after paying?

Checkout is handled securely by Payhip. The download is available immediately on the confirmation screen and is also emailed to you, so you'll always have the link.

Most boat advice comes from people selling boats. This comes from someone who cuts them open.
