Introduction

The Shimano BeastMaster 9000B is Shimano’s flagship electric reel for offshore bottom fishing. It is built for anglers who fish deep water — several hundred feet down and beyond — and want a motor to do the heavy lifting on every retrieve, while keeping the reel light enough to fish all day. If you target tilefish, grouper, snapper, or swordfish in deep water, and you are ready to move past entry-level electric reels, this is the reel Shimano positions at the top of its electric lineup.

This page covers the exact model Shimano lists as the BeastMaster 9000B (SKU BM9000B), using only the specifications Shimano publishes on its official product page. Specs below are the manufacturer’s listed figures.

Who It Fits

The BeastMaster 9000B fits anglers who:

• Fish deep drops regularly, where hand-cranking heavy weights back up is slow and tiring.
• Want a lighter electric reel — at 52.4 oz it is notably lighter than many full-size rivals.
• Want strong drag — Shimano lists a 55 lb maximum — for hard-fighting bottom fish.
• Fish from a boat with a suitable electric supply and wiring already sorted, or are willing to set that up properly.
• Are comfortable paying a premium price for a flagship electric reel — check the current price — rather than choosing a mid-range reel.

It is less suited to anglers who only drop occasionally in shallow water, who want the lowest-cost way into electric reels, or who have not yet sorted boat power and a rod that matches a large electric reel.

The Exact Package

This review covers one exact model only:

• Model: Shimano BeastMaster 9000B
• SKU: BM9000B
• Variant: Shimano’s U.S. product page lists a single BeastMaster 9000B in this line-up — there is no second size or B-variant to confuse it with.

What is in the box: Shimano’s official product page publishes a specification chart for the reel itself, but it does not publish a box-contents list. Do not assume a power cable, battery, line, or accessories are included. Before you buy, ask the seller or dealer to confirm in writing exactly what comes with the reel you will receive — reel, power cord, and any paperwork or accessories — and confirm the power supply you will need. See the purchase checklist below.

BeastMaster 9000B vs Daiwa Tanacom 1200

For the full head-to-head, see our Daiwa Tanacom 1200 vs Shimano BeastMaster 9000 comparison. The short version, from the official specs of both reels:

The BeastMaster is lighter, lists more maximum drag, and costs substantially more. The Tanacom 1200 lists more 80-lb braid capacity and a lower price. Choose the BeastMaster if you want the lighter, higher-drag flagship; choose the Tanacom 1200 if capacity per dollar matters more to you.

Installation / Purchase Checks

Work through this checklist before you buy or rig the reel:

• Confirm the exact model and SKU on the listing: BeastMaster 9000B, BM9000B — not a different BeastMaster size or generation.
• Confirm what is included in the box with the seller, since Shimano’s official page does not publish a box-contents list.
• Confirm the power supply: what cable, connector, and boat power the reel needs, and that your boat wiring can deliver it. See our Electric Reel Battery Setup & Boat Wiring Guide.
• Confirm line: pick a PowerPro strength that matches the capacity chart above (for example, 80-lb PowerPro at 1,030 yd) and your target depth.
• Confirm mounting: pair it with a rod rated for electric-reel deep dropping and check reel seat, rod holder, and rail clearance. See our Best Deep Drop Rods.
• Confirm the price, return policy, and warranty terms with the seller before paying.

Verdict

On Shimano’s own numbers, the BeastMaster 9000B is a flagship electric reel: 55 lb of maximum drag, 52.4 oz, 35 inches of line per crank, and 1,030 yards of 80-lb PowerPro capacity — check the current price. It makes the most sense for regular deep-drop anglers who want a lighter, high-drag electric reel and are prepared to pay flagship money and sort power and rigging properly. If you drop less often, or if budget and maximum line capacity matter more, the Daiwa Tanacom 1200 remains a strong, lower-priced alternative — compare them in our Tanacom 1200 vs BeastMaster comparison before deciding.
