Customer Reviews

(6 reviews)

"Accumar replaced both AC circulation pumps on my Viking — Scot 35068 motor/pumps from Depco. The new pumps are quieter and the AC is cooling better than it has in years. Same-day service, had the pumps in stock."

Captain Bill T.·48ft Viking
Jan 2026
Scot 67/68 Series 2000GPH

"Our Cruisair AC pump failed mid-summer. Roland recommended the Oberdorfer 107M as a drop-in replacement for our old Scot pump. Perfect fit, extremely quiet, and more affordable than the Scot equivalent. Great recommendation."

Mark & Lisa D.·36ft Catalina

Oberdorfer 107MB-F25

"Replaced our old freshwater pump with a Jabsco Par-Max HD5. No more pulsing at the faucets and the pressure is consistent throughout the boat. Accumar also replaced the accumulator tank — night and day difference."

Captain Steve R.·42ft Hatteras
Nov 2025
Jabsco Par-Max HD5

"Had Accumar install dual Rule 2000 GPH automatic bilge pumps with float switches. Professional wiring, proper fusing, and they added a bilge pump counter. Peace of mind knowing the bilge is covered."

Dave P.·32ft Grady-White

Rule 2000 GPH Automatic

"The Italian-made Calpeda pump Roland installed on our chilled water AC system is incredibly smooth and quiet. Much better than the old pump it replaced. Accumar knew exactly what we needed — 25 years of experience shows."

Captain Jim K.·55ft Hatteras
Sep 2025
Calpeda CM 22E-R

"Accumar installed a Reverso oil change system on our twin diesel trawler. No more messy oil changes — just flip the valve and pump. They also installed new Jabsco raw water impellers while they were at it. Thorough work."

Frequently Asked Questions

What size AC circulation pump do I need for my boat?

AC circulation pump sizing depends on your system's BTU capacity. For systems under 24,000 BTU, a small magnetic drive pump like the March MDX-3-5/8 or Little Giant 3-MD-SC works well. Systems from 24,000-72,000 BTU typically need a Scot 67/68 series or Oberdorfer 107M. Larger systems over 72,000 BTU require Scot 78 series or high-volume centrifugal pumps. Accumar Marine provides free pump sizing consultations. Call 239-323-9600.

What is the difference between Scot and Oberdorfer AC pumps?

Scot pumps (by WILO) are the OEM standard on most Cruisair and Marine Air systems — the 67/68 series are the most common marine AC pumps in the industry. Oberdorfer's 107M series are designed as direct drop-in replacements for Scot 67/68 pumps with precision machined impellers for quieter operation. Both use bronze construction and carbon/ceramic mechanical seals. We stock both brands and can recommend the best option for your system.

How much does a marine AC pump replacement cost?

Marine AC circulation pump replacement costs vary by brand and size. Accumar Marine stocks the most common pumps and can often complete same-day replacements. Call 239-323-9600 for best pricing.

Why is my marine AC not cooling properly?

The most common cause is a failing or undersized seawater circulation pump. Check for: reduced water flow from the overboard discharge, pump making unusual noise, impeller wear (rubber impellers should be replaced annually), clogged strainer basket, or a failed mechanical seal causing air leaks. Other causes include low refrigerant, dirty condenser, or thermostat issues. Accumar Marine can diagnose and repair all marine AC system components.

What freshwater pump brand is best for boats?

Jabsco Par-Max and SHURflo are the two most popular marine freshwater pump brands. Jabsco Par-Max HD series (4-6 GPM) are the industry standard for boats with multiple fixtures — they're quiet, reliable, and self-priming. SHURflo Revolution and Aqua King series are excellent budget-friendly alternatives. We install and service all brands.

How often should marine pump impellers be replaced?

Rubber impellers in raw water pumps (AC circulation, engine cooling, washdown) should be inspected every 6 months and replaced annually in Southwest Florida's warm waters. Running a pump dry for even 30 seconds can destroy a rubber impeller. Bronze impellers in centrifugal pumps (Scot, Oberdorfer) last much longer — typically 3-5 years — but should be inspected annually for wear and corrosion. Accumar Marine stocks impellers for all major brands.

What bilge pump size do I need?

ABYC recommends minimum bilge pump capacity based on boat length: under 20ft needs 500-800 GPH, 20-30ft needs 1000-1500 GPH, 30-40ft needs 1500-2000 GPH, and 40ft+ needs 2000-4000 GPH. Always install both an automatic float-switch pump and a manual backup. Rule and Jabsco are the most popular bilge pump brands. We recommend Rule 2000 GPH automatic for most boats in the 25-40ft range.

Do you service diesel transfer and oil change pumps?

Yes, we service and install diesel transfer pumps (Jabsco, Oberdorfer, Reverso), oil change systems (Reverso, Groco, Jabsco), and fuel polishing systems. Common services include pump rebuilds, impeller replacement, motor repair, and complete system installations. We also install Reverso GP-301 and GP-700 series oil change systems. Call 239-323-9600 for diesel and oil system service.
