Choosing between two Hydro-Turf standup PWC accessories can feel like comparing parts that don't line up. The 4 Inch Mounting Block with PSA is a thick foam block meant for handle pole pads, lifters, footholds, and exhaust mounting. The 1 Inch Hood Seal is a long strip made for Kawasaki stand-up hood gaps. At $31.95 and $32.95, their listed prices are only a dollar apart, but each solves a very different problem.
Quick Verdict
If you're doing a build that needs raised padding or a mounting surface, the 4 Inch Mounting Block with PSA is the more general-purpose choice. If your immediate issue is a Kawasaki hood that needs a thick seal, the 1 Inch Hood Seal is the direct fix. Each part targets a different job, so let your build direction decide.
| Product | Listed Price | Price Bar | Key Attributes |
|---|---|---|---|
| Hydro-Turf 4 Inch Mounting Block with PSA | USD 31.95 | MPN: BLOCK-04-PSA; new | |
| Hydro-Turf 1 Inch Hood Seal for Kawasaki | USD 32.95 | MPN: TS56; new; compatible with Kawasaki |
Where the 4 Inch Mounting Block Wins
Reach for this block when you need a thick mounting surface for a standup PWC build. It's the accessory that can handle a wider range of mounting jobs than a hood seal, and the included PSA means the adhesive is already there when you're ready to attach it.
Where the 1 Inch Hood Seal Wins
This is the one that's actually designed to seal a Kawasaki stand-up hood. The 1-inch-thick plush strip is 1 inch wide and 103 inches long, so it can cover a long continuous gasket run. If hood sealing is the job, this is the more targeted of the two.
Hydro-Turf Standup PWC Accessories - 4 Inch Mounting Block with PSA

If your build needs a thick block under handle pole pads or lifters, a foothold base, or an exhaust mount, this Hydro-Turf block is the direct pick. The PSA is included, so you have the adhesive ready when you mount it. The block measures 4 inches thick with a 4.7-inch by 5.1-inch footprint, which gives you a substantial mounting surface. The trade-off is purpose: this is a mounting block, not a hood seal, so it can't do the same job as the 1-inch hood seal. If your only PWC issue is a Kawasaki hood gap, this block won't solve it.
Hydro-Turf Standup PWC Accessories - 1 inch Hood Seal compatible with Kawasaki

This one is the direct answer if your standup PWC is a Kawasaki and the hood needs a new seal. The 1-inch-thick plush strip measures 1 inch wide and 103 inches long, so you get a long continuous piece for a hood gasket job. Because it's a seal rather than a mounting block, it won't do the job of the 4-inch block. The catch is that 3M self-adhesive is not included, so you'll need to provide adhesive before applying it. For Kawasaki owners who need hood sealing, this is the more targeted of the two.
Final Choice by Use Case
Choose the 4 Inch Mounting Block with PSA if you're building out padding or mounting points. Choose the 1 Inch Hood Seal if you own a Kawasaki stand-up and need a thick, long hood gasket. Both are new Hydro-Turf accessories, so the real decision comes down to which job you actually need done.
